In this paper, genetic programming (GP) based intelligent scheme is proposed for the denoising of digital images from impulse noise. Mixed impulse noise model which comprises a mixture of both salt & pepper, and uniform impulse noise, is considered. The proposed scheme works in two stages. First stage detects impulse noise in the image through a novel single-stage GP detector which is based on the extraction of robust statistical features and convolution of corrupted image with 1D Laplacian operators. The second stage consists of a GP based estimator that removes the noise by estimating the pixel value. This estimator approximates the pixel value by calculating the statistical features in the neighborhood of noise-free pixels. The idea of developing a single-stage detector and estimator is very effective in the removal of impulse noise. The proposed approach is tested on a variety of standard images and its comparison with other relevant techniques show that the performance of the proposed approach is better.
