This paper reviewed major remote sensing image classification techniques, including pixel-wise, sub-pixel-wise, and object-based image classification methods, and highlighted the importance of incorporating spatio-contextual information in remote sensing image Labeled samples are trained for supervised classification methods. Classification is a widely used technique for image processing and is used to extract thematic data for preparing maps in remote sensing applications. Post-classification comparison is a suitable method when sufficient training data is available. There are several methods and techniques for satellite image classification. The objective of image classification is to Satellite image classification methods can be broadly classified into three categories 1) automatic 2) manual and 3) hybrid. Satellite image classification methods can be broadly classified into three categories 1) unsupervised 2) supervised and 3) hybrid (Abburu and Golla, 2015). Concept of Image Classification Computer classification of remotely sensed images involves the process of the computer program learning the relationship between the data and the information classes Important aspects of accurate classification Learning techniques Feature … Several satellite image classification methods and techniques are available. Satellite image classification methods can be broadly classified into three categories 1) automatic 2) manual and 3) hybrid. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Multispectral remote sensing images are the primary source in the land use and land cover (LULC) monitoring. maps. So, for the full exploitation of multisource data, advanced analytical or numerical image fusion techniques have been developed. Unsupervised classification technique uses clustering mechanisms to group satellite image pixels into Both classifications have its own advantage and disadvantage. Comprehensive review of information extraction techniques and algorithms has not been done much, though there are lots of research attempts that are aimed at image classification [4]. Unsupervised image classification is a method in which the image interpreting software separates a large number of unknown pixels in an image based on their reflectance values into classes or clusters with no direction from the analyst (Tou, Gonzalez 1974). The present review focuses on the strengths and weaknesses of traditional pixel-based classification (PBC) and the advances of object-oriented classification (OOC) algorithms employed for the extraction of information from remotely sensed satellite imageries.

But classification is only half part of image processing and incomplete without accuracy assessment. In the following example, the Image Classification toolbar was used to classify a Landsat TM satellite image. Abstract- This paper reviews on the current trends, problems and prospects of image classification including the factors affecting it. Satellite image classification methods can be broadly classified into three categories 1) automatic 2) manual and 3) hybrid. Assessing the accuracy of the classification map is an essential area in remote sensing digital image process. The Maximum Likelihood Classification tool is the main classification method. Methods for classification-based techniques generally use geometric properties, photometric properties, and texture properties for road sections. Some methods which we will discuss in this paper are- SVM, DAG, … This is because a poorly classified map will result in inestimable errors of spatial analysis and modeling arising from the use of such data. Several classification techniques will be compared with the data, and appropriate method will be selected. All three methods have their own advantages and disadvantages. Input Landsat TM image.
