| Abstract: | The proposed approach of removal of random valued impulsive noise from images works in two phases. The first phase detects
contaminated pixels and the second phase filters only those pixels keeping others intact. The detection scheme utilizes second
order difference of pixels in a test window and the filtering scheme is a variation median filter based on the edge information.
The proposed scheme is simulated extensively on standard images and comparison with existing schemes reveal that our scheme
outperforms them in terms of Peak Signal to Noise Ratio (PSNR), number of false detection and miss detection. The proposed
scheme is also good at preserving finer details. Further, the computational complexity and number of iterations needed by the
proposed scheme is less than the existing counterparts. |
