재귀 삼방향 가중치 메디안 필터를 이용한 고밀도 임펄스 잡음 제거

다국어 초록 (Multilingual Abstract)

This paper proposes novel tri-lateral weighted median filter (TWMF) for removing the impulse noise with better edge and fine detail preservation. Instead of the specified weight of weighted median filter (WMF), we designed a novel weight function, tri-lateral weight (TW) which is the combination of domain weight (DW), range weight (RW), and edge weight (EW). The DW, RW, and EW are respectively designed to give higher weight to pixels that are spatially close to a center pixel in spatial domain, similar to the mean pixel value of filter window in intensity domain, and on edge direction with high possibility in the filter window. For ensuring high accuracy of noise reduction, iteration process is performed in TWMF by increasing the size of filter window. Simulation results indicate that our method provides superior noise reduction performance than the existing techniques.
