Description: The image is logarithmic, exponential gradation transformation. A logarithmic transformation of the low gradation area expanded, compressed high gradation area, the low area gradation image can be more clearly displayed. The exponential transformation is generally used for high grayscale image area to give greater expansion. Source package gives the source code and images to be processed, 1,4 two were too bright too dark map, after corresponding conversion can get better results.
