Dear colleagues pls help me find the article which describes the issue which appear while processing:retinex,Clahe etc defects appear at the boundaries of objects defects: halo bands on smooth gradients.
In file Clahe matlab tile size 64*64 clip limit 0.02
and 16*16 clip_limit 0.02
Why deffect could be in gradient and depend tile size(local contrast tile size ), and clip limit depend??

So color rather contrast smoothing (to blend) is a huge criteria Ivan .
