Re: statistical image enhancement

I'll have another go as the last message was cut off. Under Operations>Color Correction is the menu is an item called Statistical Image Enhancement. When you open it it shows you a formula and asks you to nominate a value for k. Can you tell me what is this formula actually doing  in regard to the manipulating the image.

Re: statistical image enhancement

I must admit that I don't really remember. It is some kind of local contrast gain based on the local standard deviation in a 15x15 pixel window.
I once made a note that it is based on an algorithm in "Digital Image Processing" by Gonzalez & Woods, page 184  smile
