Paper Abstract

A novel switching-based filter is proposed in this work to remove the impulse noise from the corrupted image. First, samples in 5×5 filter window are fully considered to detect whether the center is corrupted by impulse noise or not. Then, the detected noise free samples in the 5×5 filter window, aligned in the main direction, are weighted more heavily than those that are not on the main direction when using the median operation to suppress the impulse noise. At last, simulation results demonstrated that this algorithm outperforms many other methods in terms of both quantitative and qualitative aspects.
