Noise-adaptive rational filter

A new rational filter (RF), called noise-adaptive rational filter (NARF), is de- veloped in this thesis to deal with image smoothing in non-impulsive noise (e.g., Gaussian noise) environment. In our development, one-dimensional optimal NARF is first derived that yields the least mean-square error. F...
