Image segmentation is an important step in image processing ( image processing). The main purpose of segmentation is to simplify and or to change the representation of an image into a form that is easier to analyze. Already there are several methods of image segmentation are found , but most of these methods are not suitable for satellite imagery and -Method method requires a knowledge of the initial ( a priori knowledge) . To overcome these problems , a satellite image segmentation method is developed using an artificial neural network method without learning ( unsupervised ) called ...
