Title: IMAGE HISTOGRAM MAPPINGS
Abstract:
An example system includes a histogram engine. The histogram engine is to generate a target histogram based on a target image. The example system also includes a dispersion engine to calculate a dispersion of the target histogram. The example system also includes a spreading engine to diffuse a reference histogram for a reference image based on the dispersion of the target histogram. The histogram engine also is to generate a mapping between the reference histogram with diffusion and the target histogram.
