Satellite Image Denoising using Discrete Wavelet Transforms

The paper ?Enhancement of Satellite image Using Discrete Wavelet Transforms? makes use of both wavelet and adaptive histogram equalization techniques[7]. It is performed by make use of satellite images.By implementing this paper, enhancement is performed by increasing the resolution as well as its contrastThus the output image obtained is sharpened and is free from noisy content. First DWT[1] is applied to the input image, it decomposes the image into different frequency subbands.Apply bicubic interpolation to these subbands.Here an intermediate state is proposed for preserving more edge contents.Inorder to remove the noisy contents in the image here it uses adaptive histogram equalization technique. Thus a resolution enhanced denoised image is obtained using wavelet transform.
