In this modern world where images are considered to be the mode of communication among people and the presence of noises in images can affect the information, which is present in that images, to retain back the original information wavelet transformation and wavelet packet transformation can be used.This paper deals with the comparative result of image denoising using Wavelet Transformation and Wavelet Packet transformation with gaussian noise using thresholding technique, in order to have look on the transformation that can provide the better result to get back the original information of images, the comparative result is measured by Peak signal to noise ratio (PSNR) and mean square value (MSE).
