What Haskell representation is recommended for 2D, unboxed pixel arrays with millions of pixels?

Question

I want to tackle some image-processing problems in Haskell. I\'m working with both bitonal (bitmap) and color images with millions of pixels. I have a number of questions:

Answer 1

Although, this doesn't exactly answer your question and isn't really even haskell as such, I would recommend taking a look at CV or CV-combinators libraries at hackage. They bind the many rather useful image processing and vision operators from the opencv-library and make working with machine vision problems much faster.

It would be rather great if someone figures out how repa or some such array library could be directly used with opencv.
