An Algorithm to Detect Noised Pixel in Image

Abstract

In this paper, aim to salt and pepper noise, a new detect algorithm is proposed. GA-BPN algorithm uses Genetic Algorithm (GA) to decide weights in a Back Propagation neural Network (BPN)(GA-BPN).In this paper, we used Genetic Algorithm Back Propagation neural Network GA-BPN to do image noise detect work. Firstly, this paper uses training samples to train a GA-BPN as noise detector. Then, we utilize the well-trained GA-BPN to recognize noise pixels in target image. Experiment data shows that this algorithm has good performance.
