AB  - The drawback of losing high-frequency components suffers the resolution enhancement. In this project, the wavelet domain based image resolution enhancement technique using Tetrolet Transform (TT) is proposed for resolution enhancement of the satellite images. Input images decomposed by using FT in this proposed enhancement method. Inverse TT is used to generate a new resolution enhanced image from the interpolation of high-frequency subband images and low-resolution image from an input. Intermediate stage has proposed for estimating the high-frequency subbands to achieve a sharper image. It has tested on benchmark images from the public database. Peak Signal to Noise Ratio (PSNR) shows the preeminence of the proposed technique over the expected and state-of-art image resolution enhancement technologies.
