In mixed or hybrid pixel-based classification, individual image pixels are analysed by the spectral information that they contain. This is the traditional approach to classification since the pixel is the fundamental (spatial) unit of a satellite image, and consequently it comes naturally and is often easy to implement. Various schemes are in use in pixel-based classification. Maximum-likelihood, Minimum-distance-to-mean, and Minimum-Mahalanobis-distance are three of these. Object based classification based on both spectral and spatial information. The process involves categorization of pixels based on their spectral characteristics, shape, texture and spatial relationship with the surrounding pixels. Neural based classification is a highly developed classification scheme of image classification which usage different algorithms and back propagation method.
