Improved Image Denoising Scheme Based On Wavelet Thresholding

Abstract: Hitherto the methods discussed on image denoising are based on either transform or spatial domain which works on the noisy coefficients and try to minimize the effects of noise and improve the quality of the input. This paper is the step towards that, the method proposed here is a transform based wavelet denoising scheme found to improve the performance of the image. The thresholding are done by block matching approach.
