Satellite images are used in many research fields. The main problem with the satellite images are their low resolution and blurring effects. Thus, in order to use these images, we need to enhance their quality. Thus, in this paper we have described various wavelet transform techniques such as WZP (Wavelet Zero Padding), CS-WZP (Cyclic Spinning WZP), UWT (Undecimated Wavelet Transform) and DWT (Discrete Wavelet Transform). These all are wavelet transform techniques which are used for image resolution enhancement. In these all techniques and algorithms, we give a low resolution image obtained from any satellite image as the input and get a high resolution image as the output. The comparison of these techniques is made based on two factors MSE (Mean Squared Error) and PSNR (Peak Signal to Noise Ratio).
