Abstract
Current switching-based median filters are commonly found to be incapable to find exact noise density variations and prone to misclassifying pixel characteristics at high noise density interference. Therefore there is a need of having a sophisticated switching weighted median filter. In this paper, we propose a directional based detection technique called the directional weighted median filter (DWMF), to achieve much improved filtering performance in terms of effectiveness in removing impulse noise while preserving signal details and robustness in combating noise density variations.
