However, when noise level increased, or with thin edges, median filter may work poorly. This paper proposes a new filter, which will detect edges along four possible directions, and then replace noise corrupted pixel with estimated noise-free edge median value. Simulations show that the proposed multi-stage directional median filter can provide excellent performance of suppressing impulse noise in all situations.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {3}, number = {11}, year = {2009}, pages = {2094 - 2097}, ee = {https://publications.waset.org/pdf/143}, url = {https://publications.waset.org/vol/35}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 35, 2009}, }
