Satellite images are being used in various research areas of medical, remote sensing, defense, meteorology, geographic studies and various other industries. The need for image enhancement is one of the major challenges in image processing. In this paper a study of various image resolution enhancement methods in wavelet domain is done. Visual appearance of an image and image quality can be improved by the various enhancement techniques. Some spectral and spatial problems still prevail in satellite images such as motion blur and poor perception. The super resolution images are obtained by applying enhancement techniques on noisy and blurred images. In this paper, some of the resolution enhancement techniques such as Discrete Wavelet Transform, Wavelet Zero Padding, Cycle Spinning, and Dual Tree-Complex WT which improves the visual appearance of the images are highlighted.

Cycle Spinning, Discrete Wavelet Transform, Dual Tree-Complex Wavelet Transforms, High Resolution, Low Resolution, Undecimated Wavelet Transform, Wavelet Zero Padding.
