CONTRAST FOR RGB IMAGES IN A GIS APPLICATION

机译:GIS应用程序中RGB图像的对比

摘要

Disclosed herein is a method and system for performing normalization of an image using a cumulative histogram and a common color map for the R, G and B channels. On receiving an instruction from a user to normalize an image, the histogram for individual channels of the image is computed. The cumulative histogram from the histogram for individual channels is computed. The linear histogram cut off percentage is tripled. The min and max positions using the histogram stretch after the percentage cutoff is adjusted. The colormap is computed using the cumulative histogram and the linear histogram cut off percentage. The colormap is applied to the image data.
