IMPULSE NOISE DETECTOR BY USING LAPLACIAN-GAUSSIAN FILTER

In this work, we propose a new impulse noise detecter from images using Laplacian-Gaussian(L-G) filter. In our system, the L-G filter separates tha edge from the flat. The threshold for noise detection is set to large in the edge. On the other hand, that is set to small in the flat. Consequently, the performance of the noise detector is improved. Extensive simulations indicate that proposed method performs significantly better than traditional methods.
