Abstract: To remove the random impulse niose introduced during the signal trsansmission and acquisition, a new vector median filter algorithm based on fuzzy reasoning is proposed. The approach utilizes the fuzzy rules to judge whether details exist in current filtering window. Different filter methods are adopted according to the fuzzy reasoning result. When not being regarded as noise pixel, the original pixel is retained. The experiments show that the fuzzy filter algorithm outperforms other state-of-the-art filters.
