Use of multiple or multiscale texture images should be in conjunction with original spectral images to improve classification results (Kurosu et al. Spectral shape classification of Landsat Thematic Mapper imagery. 1997, Cortijo and de la Blanca 1997, Flygare 1997, Michelson et al. Some advanced techniques use laser imaging, fluorescent imaging, and spectroscopy for defect detection. The eCognition method is so far the most commonly used object‐oriented classification (Benz et al. Downloading of the abstract is permitted for personal use only. Recently, the geostatistic‐based texture measures were found to provide better classification accuracy than using the GLCM‐based textures (Berberoglu et al. The huge amount of data storage and severe shadow problems in fine spatial resolution images lead to challenges in the selection of suitable image‐processing approaches and classification algorithms. Accuracy assessments of hyperspectral waveband performance for vegetation analysis applications. 2002, Zhang et al. Multiple criteria for evaluating machine learning algorithms for land cover classification from satellite data. A regional measure of abundance from multispectral images. 2003), but the large volume of data often generates a challenge for image processing and classification. Advanced non‐parametric classifiers, such as neural network, decision tree, evidential reasoning, or the knowledge‐based approach, appear to be the choices. One of the approaches is to develop knowledge‐based classifications based on the spatial distribution pattern of land‐cover classes and selected ancillary data. 2001, Du et al.

Evaluation of the grey‐level co‐occurrence matrix method for land‐cover classification using SPOT imagery. Sorting of fruits can be done mostly based on their characteristics such as the colour of the fruit, size, surface irregularities. In order to properly generate an error matrix, one must consider the following factors: (1) reference data collection, (2) classification scheme, (3) sampling scheme, (4) spatial autocorrelation, and (5) sample size and sample unit (Congalton and Plourde 2002). Image fusion techniques for remote sensing applications. 1997), and a combination of neural network and statistical approaches (Benediktsson and Kanellopoulos, 1999, Bruzzone et al.

Evaluating the degree of fuzziness of thematic maps with a generalized entropy function: a methodological outlook. Table 4 summarizes major approaches for combining various ancillary data and remote‐sensing imagery for image classification improvement. images has created the need for efficient and intelligent schemes for image classification. Medium spatial resolution data such as Landsat TM/ETM+ or coarse spatial resolution data such as AVHRR and MODIS are attributed to the L‐resolution model. Many potential variables may be used in image classification, including spectral signatures, vegetation indices, transformed images, textural or contextual information, multitemporal images, multisensor images, and ancillary data. Cihlar (2000) discussed the status and research priorities of land‐cover mapping for large areas. In summary, the error matrix approach is the most common accuracy assessment approach for categorical classes. (2001) summarized three primary sources of errors: errors introduced through the image‐acquisition process, errors produced by the application of data‐processing techniques, and errors associated with interactions between instrument resolution and the scale of ecological processes on the ground. Accuracy assessment based on error matrix is the most commonly employed approach for evaluating per‐pixel classification, while fuzzy approaches are gaining attention for assessing fuzzy classification results. Multitemporal land‐cover classification using SIR‐C/X‐SAR imagery. A practical look at the sources of confusion in error matrix generation. In addition to object‐oriented and per‐field classifications, contextual classifiers have also been developed to cope with the problem of intraclass spectral variations (Gong and Howarth 1992, Kartikeyan et al. Spectral unmixing of hyperspectral imagery for mineral exploration: comparison of results from SFSI and AVIRIS. The spectral features include the number of spectral bands, spectral coverage, and spectral resolution (or bandwidth). 2003, Benz et al. Solberg et al. An assessment of the effectiveness of decision tree methods for land cover classification. In this situation, economic condition is often an important factor that affects the selection of remotely sensed data and the time and labour that can be devoted to the classification procedure, thus affecting the quality of the classification results. Synergy of multitemporal ERS‐1 SAR and Landsat TM data for classification of agricultural crops. Remote‐sensing data are more uniform than ancillary data, which vary in data format, accuracy, spatial resolution, and coordinate systems. 2004). Contextual classification exploits spatial information among neighbouring pixels to improve classification results (Flygare 1997, Stuckens et al. This section focuses on the description of the major steps that may be involved in image classification. Optimization of multisource data analysis: an example using evidential reasoning for GIS data classification. Then the classification was done for different selections of the spectral bands with the spectral angle mapper (SAM) and support vector machine (SVM) on hyperspectral Indian Pine image. Three strategies for the integration can be distinguished (Ehlers et al. TM and IRS‐1C‐PAN data fusion using multiresolution decomposition methods based on the ‘à trous’ algorithm. These techniques have been used in decision trees (Friedl et al. 1993, Franklin et al. Comparing with non-incremental learning model in literature, the incremental learning method improves the computation efficiency of nearly 90%. 1999a,b, Dean and Smith 2003). The spatially neighbouring pixel information is used in image classification. 2001, Lu and Weng 2004). maximum likelihood) and non‐parametric classifiers (e.g. Whether parameters such as mean vector and covariance matrix are used or not. Neural classification of SPOT imagery through integration of intensity and fractal information. 2000, Hubert‐Moy et al. Previous research has indicated that post‐classification processing is an important step in improving the quality of classifications (Harris and Ventura 1995, Murai and Omatu 1997, Stefanov et al. The performance of the system is further enhanced by the N-best hypotheses search, coupled with duration constraint. 1998a, Mustard and Sunshine 1999, Lu et al. The comparison of activation functions for multispectral Landsat TM image classification. 2004, Walter 2004), which does not require the use of GIS vector data. Fusion of airborne polarimetric and interfermetric SAR data for classification of coastal environments. The availability of high‐quality remotely sensed imagery and ancillary data, the design of a proper classification procedure, and the analyst's skills and experiences are the most important ones. Non‐parametric classifiers do not employ statistical parameters to calculate class separation and are especially suitable for incorporation of non‐remote‐sensing data into a classification procedure. I. Subpixel classification of Bald Cypress and Tupelo Gum trees in Thematic Mapper imagery. Harris and Ventura (1995) and Williams (2001) suggested that ancillary data may be used to enhance image classification in three ways, through pre‐classification stratification, classifier modification, and post‐classification sorting. A relative evaluation of multiclass image classification by support vector machines. Selection of a suitable classifier requires consideration of many factors, such as classification accuracy, algorithm performance, and computational resources (DeFries and Chan 2000). Different classification methods have their own merits. In practice, making full use of the multiple features of different sensor data, implementing feature extraction, and selecting suitable variables for input into a classification procedure are all important. In last few years, the complexity of multimedia contents, especially the images, has grown exponentially, and on daily basis, more than millions of images are uploaded at different archives such as Twitter, Facebook, and Instagram. Among the most commonly used non‐parametric classification approaches are neural networks, decision trees, support vector machines, and expert systems. The spectral characteristics of land surfaces are the fundamental principles for land‐cover classification using remotely sensed data. 1997, Tokola et al. Using shade fraction image segmentation to evaluate deforestation in Landsat Thematic Mapper images of the Amazon region. Use of GIS in improving classification performance, Merging of IRS LISS III and PAN data—evaluation of various methods for a predominantly agricultural area. 2004) and influences the selection of classification approaches (Atkinson and Curran 1997, Atkinson and Aplin 2004). These criteria include classification accuracy, computational resources, stability of the algorithm, and robustness to noise in the training data. 2004). 1. 3099067 A suitable classification system and a sufficient number of training samples are prerequisites for a successful classification. 2001, Lu and Weng 2004). 1998a, Lu et al. As multisource data become easily available, the integration of remote sensing and GIS is emerging as an appealing research direction that can be applied to image classification. Uncertainty may be modelled or quantified in different ways such as fuzzy and probabilistic classification techniques, or via visualization (van der Wel et al. The number of spectral bands used for image classification can range from a limited number of multispectral bands (e.g. Document image classification is an important step in Office Automation, Digital Libraries, and other document image analysis applications. Mapping deciduous forest ice storm damage using Landsat and environmental data. This is particularly useful for areas such as moist tropical regions, where adverse atmospheric conditions regularly occur. Mapping vegetation in Yellowstone National Park using spectral feature analysis of AVIRIS data. Combining non‐parametric models for multisource predictive forest mapping. To evaluate the performance of a classification method, Cihlar et al. Texture ... many approaches used for texture classification [2]. In practice, the spatial resolution of the remotely sensed data, use of ancillary data, the classification system, the available software, and the analyst's experience may all affect the decision of selecting a classifier. 1999a,b, Aplin and Atkinson 2001, Dean and Smith 2003, Lloyd et al. 1994, Chavez 1996, Stefan and Itten 1997, Vermote et al. ECHO, combination of parametric or non‐parametric and contextual algorithms. Fuzzy ARTMAP supervised classification of multi‐spectral remotely‐sensed images. Many factors, such as spatial resolution of the remotely sensed data, different sources of data, a classification system, and availability of classification software must be taken into account when selecting a classification method for use. For fine spatial resolution data, although mixed pixels are reduced, the spectral variation within land classes may decrease the classification accuracy. For medium and coarse spatial resolution data, however, spectral information is a more important attribute than spatial information because of the loss of spatial information. A critical step is to develop approaches to identify the best appropriate variables that are most useful in separating land‐cover classes (Peddle and Ferguson 2002). Selection of a suitable sampling strategy is a critical step (Congalton 1991). Spectral mixture analysis of the urban landscapes in Indianapolis with Landsat ETM+ imagery. This paper examines current practices, problems, and prospects of image classification. Strahler et al. Analysis of classification results of remotely sensed data and evaluation of classification algorithms. (1996) broadly divided data fusion methods into four categories: statistical, fuzzy logic, evidential reasoning, and neural network. It evaluates each pixel spectrum as a linear combination of a set of endmember spectra (Adams et al. 1990, Kartikeyan et al. Similarly, temperature, precipitation, and soil data are related to land‐cover distribution at a large scale. Visual exploration of uncertainty in remote sensing classification. 1982, Civco 1989, Colby 1991, Meyer et al. The recognition rate improves from 97.7% in binary system to 99.9% in gray-level with modified N-best search, over a testing set with similar blur and noise condition as the training set. 2004, Gitas et al. In this literature survey, we have briefly introduced a number of typical DL models that may be used to perform RS image classification, including: CNNs, SAEs and DBNs. Data fusion involves two major procedures: (1) geometrical co‐registration of two datasets and (2) mixture of spectral and spatial information contents to generate a new dataset that contains the enhanced information from both datasets. An alternate way of integrating multiresolution images, such as Landsat TM (or SPOT) and MODIS (or AVHRR), is to refine the estimation of land‐cover types from coarse spatial resolution data (Moody 1998, Price 2003). The methods, including colour‐related techniques (e.g. II. 663 with the cover-frequency method. Maximizing land cover classification accuracies produced by decision trees at continental to global scales. A comparison of spatial feature extraction algorithms for land‐use classification with SPOT HRV data. 1998). The question of which classification approach is suitable for a specific study is not easy to answer. Another major drawback is that it is difficult to integrate ancillary data, spatial and contextual attributes, and non‐statistical information into a classification procedure. In addition, some important issues affecting classification performance are discussed. Mixture density separation as a tool for high‐quality interpretation of multi‐source remote sensing data and related issues. 1999, Woodcock and Gopal 2000), symmetric index of information closeness (Foody 1996), Renyi generalized entropy function (Ricotta and Avena 2002), and parametric generalization of Morisita's index (Ricotta 2004) have been developed. The captured images must be understood for diagnosis, prognosis and treatment planning of the anomalies. The second method is to implement data fusion through the use of higher spatial resolution (e.g. In particular, different visualization techniques, such as geovisualization and interactive visualization, have proven helpful for uncertainty study in image classification (MacEachren and Kraak 2001, Bastin et al. Hyperspectral mixture modeling for quantifying sparse vegetation cover in arid environments. The fraction images are related to biophysical characteristics, and thus have the potential for improving classification (Roberts et al. Landsat TM) (Yocky 1996, Shaban and Dikshit 2002) in order to enhance the information contents from both datasets. 1995, Hoffbeck and Landgrebe 1996, Platt and Goetz 2004, Thenkabail et al. 5 Howick Place | London | SW1P 1WG. Similarly, geometric rectification or image registration between multisource data may lead to position uncertainty, while the algorithms used for calibrating atmospheric or topographic effects may cause radiometric errors. 2001, Shaban and Dikshit 2001, Narasimha Rao et al. Temporal resolution refers to the time interval in which a satellite revisits the same location. Classification accuracy assessment is, however, the most common approach for an evaluation of classification performance, which is detailed in §3. Spectral texture for improved class discrimination in complex terrain. Contextual classification of Landsat TM images to forest inventory cover types. A survey of medical image classification techniques Abstract: Medical informatics is the study that combines two medical data sources: biomedical record and imaging data. Object‐based image classification for burned area mapping of Creus Cape Spain, using NOAA‐AVHRR imagery. This literature review suggests that designing a suitable image‐processing procedure is a prerequisite for a successful classification of remotely sensed data into a thematic map. Graphic analysis (e.g. 2001, Lucieer and Kraak 2004). Random crops of 227 × 227 pixels from the input image of size 256 × 256; Randomly mirror images in each forward-backward training pass; When predicting, the network expects face image, cropped to 227 × 227 around the face center. Data on terrain features are thus useful for separation of vegetation classes. sub‐pixel land cover mapping for per‐field classification. This paper examines current practices, problems, and prospects of image classification. Comparative studies of different classifiers are thus frequently conducted. Keywords - Convolution Neural Networks, Deep Learning, Image Processing, Segregation, Support Vector Machine, Waste Classification. Research in autonomous navigation was done from as early as the 1900s with the first concept of the automated vehicle exhibited by General Motors in 1939. Subpixel classification approaches have been developed to provide a more appropriate representation and accurate area estimation of land covers than per‐pixel approaches, especially when coarse spatial resolution data are used (Foody and Cox 1994, Binaghi et al. Radiometric corrections of topographically induced effects on Landsat TM data in alpine environment. 2002, McGovern et al. MultiSpec—a tool for multispectral‐hyperspectral image data analysis. The main motive of this literature survey is to give a brief comparison between different image classification techniques and methods.

Visual categorization with aerial photography. Sasi Kiran1, N. Vijaya Kumar 2, N. Sashi Prabha 3, M. Kavya4 Department of Computer Science and Engineering Vidya Vikas Institute of Technology, Chevella, R.R. 1999) and have been used for image classifications (Gordon and Phillipson 1986, Franklin and Peddle 1989, Marceau et al. 2004). Making full use of these characteristics is an effective way to improve classification accuracy. Spectral features are the most important information for image classification. Gaussian distribution is assumed. Classification by progressive generalization: a new automated methodology for remote sensing multispectral data. Whether spatial information is used or not.

Imaging techniques are used to capture anomalies of the human body. Classification trees: an alternative to traditional land cover classifiers. Another important use of ancillary data is in post‐classification processing for modifying the classification image based on the established expert rules as discussed previously. 2000, Schmidt et al. Use of the average mutual information index in evaluating classification error and consistency. Integration of remote sensing with geographic information systems: a necessary evolution. Soft classification provides more information and potentially a more accurate result, especially for coarse spatial resolution data classification. Penaloza and Welch (1996) explored the fuzzy‐logic expert system for feature selection. The error matrix approach is only suitable for ‘hard’ classification, assuming that the map categories are mutually exclusive and exhaustive and that each location belongs to a single category. 2003) and is especially important for improving area estimation of land‐cover classes based on coarse spatial resolution data. Monitoring the composition of urban environments based on the vegetation‐impervious surface‐soil (VIS) model by subpixel analysis techniques. Another major drawback of the parametric classifiers lies in the difficulty of integrating spectral data with ancillary data. Classification algorithms can be per‐pixel, subpixel, and per‐field. Classification using ASTER data and SVM algorithms: the case study of Beer Sheva, Israel. However, difficulties still exist in data integration due to the differences in data structures, data types, spatial resolution, geometric characteristics, and the levels of generation (Wang and Howarth 1994).
