GrayToColor takes grayscale images as input and assigns them to colors in a red, green, blue (RGB) image or a cyan, magenta, yellow, black (CMYK) image. Each color’s brightness can be adjusted independently by using relative weights.
Enhances the global contrast by equalizing the histogram. This plugin transforms pixel intensities so that they are uniformly distributed over the gray-scale range. It operates on the selected channel of each image of a sequence. This operation is also called "histogram flattening".
