Paper presents directional weighted median base fuzzylter for random- valued impulse noise removal. In order to detect noise efficiently a fuzzy noise de- tection process is used whereas noise removal is performed by the directional weighted median based fuzzyltering process. Proposed technique is compared with existing tech- niques based on peak-signal-to-n oise-ratio (PSNR) and structural similarity index mea- sure (SSIM). Simulations show that the noise removal capability of the proposed technique is much better than the existing techniques.
