Algorithm of super-resolution in images and video sequences applying wavelets based on atomic functions

Abstract

A novel algorithm for super resolution (SR) in images and video sequences is introduced. In difference with conventional approaches, new framework employs the spatial spectral properties of an image or sequence applying wavelet technique. Novel wavelets based on atomic functions used in SR have shown good properties of resolution by extension of an image size up to 4 times in comparison with the original low resolution image. Numerous statistical simulations have demonstrated the effectiveness of the novel technique exposing good subjective visual quality as well as significant improvement of SR image..
