Adapthisteq - why...? #61

Closed Shrediquette closed 2 years ago

Shrediquette commented 2 years ago

Why do I use adapthisteq (which divides the image into subregions and stretches the histogram)? Why don't I just use imadjust on every interrogation area...? Which one is faster and which gives more robust results?

Shrediquette commented 2 years ago

[,T] = histeq() also returns the transformation T that maps the gray component of the input grayscale image or color map to the gray component of the output grayscale image or color map.

Maybe also link the transformation of A and B?

Shrediquette commented 2 years ago

Grayscale image, specified as a numeric array of any dimension.

Operates directly on 3D data.

I might skip adapthisteq and also imadjust in the pre-processing.

No advantage
