image classification(Processing techniques which apply quantitative methods to the values in a digital yield or remotely sensed scene to group pixels with similar digital number values into feature classes or categories)
image enhancement(In remote sensing, the filtering of data and other processes to manipulate pixels to produce an image that accentuates features of interest or visual interpretation)
image processing(The process of converting "raw" remotely sensed data into a usable form through the application of various transformations such as supervised and unsupervised classification schemes)
image processing digital system(A coordinated assemblage of computer devices designed to capture and manipulate pictures stored as data in discrete, quantized units or digits)
