Images often corrupted by various noises during the process of generation and transmission. Mostly Images are corrupted by impulse noise & Gaussian noise. There are several methods to remove noises from different types of images. But still noise removal is a challenging task in order to obtain better recognition rate. So, keeping in view, a new hybrid approach for image denoising is presented, which is hybridization of wavelet filter and median filter. This hybrid method is proposed for denoising multiple noise (Gaussian and Impulse) images. To quantitatively evaluate and prove the performance of the new method, series of comparisons with some existing denoising methods are carried out in the paper and performance parameters are calculated such as MSE(Mean Square error), PSNR (Peak Signal to Noise Ratio).
