摘要：This paper deals with the threshold estimation techniques in the wavelet transform domain filtering for image denoising. Wavelet transform based image denoising techniques are of greater interest due to its excellent localization property. The aim of this paper is to present an improved threshold in comparison of universal hard threshold which gives a better result by preserving the original image details. As a numerous papers have been published to restore an image from noisy distortions but selecting an appropriate threshold plays a major role in getting the desired image. Our improved threshold is a forward step towards this approach.
