A method of impulse noise detection
by using Laplacian-Gaussian Filter <Abstract> 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 switched at the edge and the flat. Moreover, parameters are adopted by Genetic Algorithm. Consequently, the performance of the noise detector is improved. Extensive simulations indicate that proposed method performs significantly better than traditional methods. |
