Research on a novel adaptive window for image filter algorithm
A novel on-off image filter algorithm is introduced in this paper, whose shape, size and orientation can vary with the image's regional structure. The filter window's size vary with the corresponding pixel's gradient magnitude, and it's shape, orientation is adjusted in such a way as to lie in the direction of the least gradient. Meanwhile, a criterion and flowchart which can classify pixels into noise-pixels and structure pixels is also proposed. Compare with the traditional mean filter, the traditional median filter and the method of an adaptive smooth filter algorithm of still images, the simulation results prove that the proposed adaptive window image filter algorithm have a better resolution and it can protects image's structure more well.
