Real-time image filtering scheme based on robust estimators in presence of impulsive noise

Abstract

This paper presents the capability and real-time processing features of a robust filter for the removal of impulsive noise in image processing applications. The real-time implementation of image filtering was realized on the DSP TMS320C6701. Extensive simulation results with different images have demonstrated that the proposed filter consistently outperforms other filters by balancing the tradeoff between noise suppression and fine detail preservation. We simulated impulsive corrupted video sequences to demonstrate that the proposed method potentially could provide a real-time solution to quality video transmission.
