Abstract :
This paper proposes an effective resolution enhancement approach for images such as satellite images as well as normal images. In this method DT-CWT and bicubic interpolation were used. The proposed method was tested on well-known benchmark images. Finally Peak Signal to Noise Ratio (PSNR) and visual results of the proposed method out performs the state of art image resolution enhancement techniques.
