Multi Spectral Image Enhancement in Satellite Imagery

摘要

This paper describes a GUI based multi spectral image enhancement used to achieve highly realistic and geo-scientifically corrects visualizations of real satellite imagery. Quite often the useful data in a digital image populates only a small portion of the available range of digital values. Image enhancement involves changing the original values so that more of the available range is used. This then increases the contrast between features and their backgrounds. It consists of reading the binary image on the basis of pixels taking them byte wise and displaying it, calculating the statistics of an image, automatically enhancing the color of the image based on statistics calculation using algorithms and working with RGB color bands. Finally the enhanced image is displayed along with image histogram.
