Change from RGB to HSV or Ycbcr

Looking to do histogram matching. From research, the preference is to be in a color space with intensity, therefore HSV or YCbCr. I've tried RGB matching but on the darker sets of satellite images, it does not match well when its 'brightness' increases. 

 

 

Is there something I can do/use in FME to convert from RGB to HSV ?

 

Can I do this in python? Read in a feature and output a HSV image?

hi @pat8037, may be you get some inspiration from this website: http://www.rapidtables.com/convert/color/rgb-to-hsv.htm. I also attached a workbench implementation. Just a bunch of AttributeCreators, basically.
