Title: Detail Preserving Sorted Difference Filter
Authors: Tieling Chen
Abstract: A detail preserving filter that uses the intensity differences between a pixel and its neighbor pixels to eliminate impulse noises with minor variations is proposed. The absolute values of the intensity differences are sorted into a sequence in ascending order and the value at a specific position is used to determine whether the pixel under processing is an impulse noise or not. The method to find the specific position is provided and its feasibility is discussed. Theoretically impulse noises can be correctly selected when the density of the noises are not heavy. The filter preserves more fine details than the standard median filter in general. In the situation when the distribution of impulse noises has minor variations, the filter works better than the commonly used adaptive median filter and also produces cleaner results.
