I have found the following two books useful. The fundamental algorithms in image processing can be found in this free book "Image Processing in C" while the fundamental computer vision algorithms can be found in this free book "Introduction to Computer Vision" by Prof. Mubarak Shah, one of the pioneers in this area. Both books are available on Sciweavers.
