reference for rational filter:

1. a simple algorithm for the reduction of blocking artifacts
in images and it's implementation.1998 aug

2. design and implementation of 3D rational filter for edge
preserving smoothing.

For others: the book

Digital Image Processing by Gonzalez and Woods can be a good
start point.
