Abstract
In this paper, we present the real-time implementation of image filtering for impulse and mixture of impulsive and multiplicative noise removal with detail preservation by means of use of DSP TMS320C6701. The filtering scheme is given for two filters connected in cascade. In the first stage, we use the MM-KNN (Median M-type K-Nearest Neighbor) filter to provide detail preservation and impulsive noise rejection. The second stage is proposed to use an M filter to provide multiplicative noise suppression. We use different types of influence functions in the M-estimator to provide better noise suppression. Extensive simulation results demonstrate that the proposed filter consistently outperforms other filters by balancing the tradeoff between noise suppression and detail preservation.
