algorithms for image processing

[priyanka]

i want to need logic and algorithms for resize,rotation,indexing,flip,flop,solerizing,colorizing,gamma paint of image.my project is "image processing" in the linux platform using shall script.and i performing above such function in this. so i need algorithms and logic behind such functions.please help me to find logic and algorithms of those function.

You are asking for enough information to fill a whole library of books, and full University Degree!

For specifics, many operators described in IM Examples, also contain alternatives and examples that try to explain exactly what that operation does to an image.

Solarise for example, is just a direct color value modifier. It basically starts to subtract color values that are larger than some threshold.

Distorting images is very complex, but a explanation starting from simple 'novice' distortions to complex EWA distortions are also explained...

resize filters are harder still to explain.

A good introduct is on the web in, these are my bookmarks on them...
