Nonlinear filters have been applied in image restoration. In nonlinear filters, a neural filter was proposed for reducing mixed Gaussian and impulse noises. However, in the case of mixed Gaussian and high probability impulse noises, the performance of neural filter is significantly reduced. In this paper, we propose a filter for removing mixed impulse and Gaussian noises using Trimmed filter and neural filters. Carrying out the simulation, we illustrate the peak signal to noise ratio of the proposed filter, and show that it is effective in removing mixed impulse and Gaussian noises.
