Satellite images are being used in many applications like Meteorology, Agriculture, Geology, Forestry, Landscape, Biodiversity, Planning, Education, Regional, Seismology and oceanography. The Enhanced satellite images make diagnostic details more obvious. The Image Enhancement is the main technique for improving the resolution and visual appearance of the image. One of the major issues in Image Enhancement is Wavelet Transform. The Wavelet Transform is the method which decomposes an image into a set of basic functions called Wavelets. These basis functions are limited in duration and are inherently local. A Resolution Enhancement technique is based on the Interpolation of the high-frequency sub-bands obtained by Discrete Wavelet Transforms (DWT).
