In signal processing and image processing, many filters have been studied for smoothing images corrupted by noises. In particular, some nonlinear filters have been investigated. In nonlinear filtering, a neural filter was proposed for reducing Gaussian noise. However, a neural filter was not applied to images with impulse noise. In this paper, we propose a filter for removing impulse noise, Gaussian noise and mixed impulse and Gaussian noises using median filters and neural filters. Carrying out the simulation, we illustrate the performance of the proposed filter.
