Conversion of Low Resolution Video into High Resolution Video using Super-resolution in Wavelet Domain

Tanuja J Salunke, V. B. Baru

Abstract: Super-resolution is a class of techniques that enhance the resolution of an imaging system. The technique of image super-resolution (SR) has been extensively studied to solve the problem of limited resolution in imaging devices since many years. In this paper, image super-resolution method in wavelet domain is applied for conversion of low resolution video into high resolution video. The proposed resolution enhancement technique uses spatio-temporal wavelet transform to decompose the input image into different sub bands. The peak signal-to-noise ratio (PSNR) and visual results of the image show the superiority of the proposed method over the conventional image resolution enhancement techniques.

Keywords: Super-resolution, Spatio-temporal wavelet transform, Interpolation, PSNR
