In unsupervised classification, image processing software classifies an image based on natural groupings of the spectral properties of the pixels, without the user specifying how to classify any portion of the image. The Unsupervised Classification process assigns class numbers in the order in which the classes are created. The ISODATA clustering method uses the minimum spectral distance formula to form clusters. 571 34 Unsupervised classification is where the outcomes (groupings of pixels with common characteristics) are based on the software analysis of an image without the user providing sample classes. . 0000039978 00000 n Unsupervised Classification.
