Copy Code Copy Command This example shows how to plot the transformation curve for histogram equalization. histeq can return a 1-by-256 vector that shows, for each possible input value, the resulting output value. (The values in this vector are in the range [0,1], regardless of the class...

This MATLAB function enhances the contrast of the grayscale image I by transforming the values using contrast-limited adaptive histogram equalization (CLAHE) [1].
Histogram equalization can be applied to the current frame where the accumulated histogram was calculated, or the frame after. If applying to the current frame, the input video needs to be stored. This example delays the input video by one frame and performs uniform equalization to the original...

Mapping technique used to map the histogram ofrefto imageI, specified as one of these values: "uniform"— Use a histogram-based intensity function and histogram equalization. "polynomial"— Calculate a cubic Hermite polynomial mapping function from the cumulative histograms of the source and referenc...
adapt histogram equalization- claheIt's hard to diagnose unseen code, but based on the extreme contrast in the output image, I'd suspect that you're operating at some point on improperly-scaled data (e.g. uint8-scale float instead of unit-scale float). If that's the case, it's not...
