Color enhancement algorithm for remotely sensed false color image, using uniform color scale
The improved LUV algorithm could highly enhance the false color image with preserved brightness and hue sensation. The resulting pictures met with approval. The algorithm was implemented as a library software and is planned to be used at Earth Resources Satellite Data Analysis Center.
There was a problem in this algorithm being used at a public center. Because this algorithm fully makes use of human color perception characteristics, displayed color should be same as that denoted by the computed (R,G,B) value. It is very important to calibrate color monitors used at the computer center so that an individual primary color brightness is proportional to each value. This problem had been also solved by the authors. Using devices calibrated in such a manner, effective display was obtained.
