What is meant by “locally adaptive” processing?
Other methods (particularly those that are “global” in nature, including histogram-based ones) tend to simply crank up the gain uniformly across the entire image. In our case, for each pixel in the image, we vary the processing based on a large local “neighborhood” of image data surrounding that pixel. This “adapts” (adjusts) the processing to best fit the needs of each pixel’s own area of the image.
