%X In order to improve the drawback of the existing image denoising algorithms which was easily to lose detail features and low peak signal-to-noise ratio PSNR, inspired by the cross breeding and learned the idea of generic algorithm, this paper proposed an image denoising method based on hybrid Bayesian wavelet transform. This algorithm took the image denoised by Bayesian wavelet threshold as male parent, and image denoised by Wiener filter as female parent to hybridize and mutate, then offspring could be generated. The offspring which meet the best standards would be decoded to be the optimal solution, and restored to be image as the best result of the algorithm. The denoised image using proposed method had much higher PSNR and better visual quality than conventional methods. The result shows that the proposed method can not only denoise effectively, but also reserve the detail features such as edge.
