ABSTRACT: In the field of image processing, various types of denoising algorithm is used to smoothen the texture of the image quality and to remove the unwanted noise such as salt and pepper noise, additive white Gaussian noise etc. In the existing work, a novel gradient histogram preservation (GHP) algorithm was developed to enhance the texture structures and exhibits the poor performance in human image detection experiments. In the proposed work Discrete Wavelet Transform (DWT) methods is used to estimate the noisy observation of an medical image to preserve the texture appearance. By experimental results peak signal noise ratio(PSNR) parameters will be calculated efficiently and make the image enhanced without noise and brings the quality of image without any loss of data by comparing the GHP and DWT to give a high performance using mat-lab simulation.
