Abstract
A method of an image resolution enhancement system based on the Undecimated Wavelet Transform (UWT), for the interpolation of the high frequency sub band images from the original input images. First the edges enhancement process is done during the intermediate stages of the wavelet transform. Then the UWT is applied, for the decomposition of different sub-band from the input image. Then the interpolation process is done between the input images and the high frequency sub-band images. This high frequency sub-band is altered by using the UWT algorithm based high frequency sub-bands. Finally the Inverse UWT (IUWT) algorithm is performed to add all the sub-bands for generating the new high resolution image which is called as the enhanced high resolution image. The Peak to Signal Noise Ratio (PSNR) is found in order test out resolution enhancement method performance.
