Good evening, I'm working with image processing. More specifically with equalization. I wonder if the library OpenCV has some method that works with the same idea of the effect(Auto-Level) in the Photoshop. I tried using the method implementation Equalize the Class(HistogramEqualizer) but only histogram equalization is not very faithful. The algorithm varies greatly according to total enlightenment or some parts of the image.
