Hue saturation transform - more possibilities

Post by pierrelabreche »

Could it be feasible to add uniformity controls to the transform ?
It would conceptually work as follows :
  • Consider the bins selected in the histogram
  • The center of gravity (CoG) of the histogram measurements in selected bin defines the average hue-saturation of the selection
  • A vector from the CoG to the image's local color measures the color difference between the CoG and the Hue-Sat of the input image
  • Controls, such as sliders, could independently adjust the image's HSV or HSL components to magnify or attenuate the difference
