Online published on 12 January, 2017. Abstract An image resolution enhancement technique which is based on the interpolation of the high frequency sub bands obtained by DWT is proposed in this paper. The proposed technique uses DWT to crumble an image into different sub bands, and then the high frequency sub band images have been interpolated. An original image is interpolated with half of the interpolation factor used for interpolation the high frequency sub bands. Afterwards all these images have been united using IDWT to produce a super determined image. The proposed technique has been experienced on well known benchmark images, where their PSNR, Mean Square Error shows the dominance of proposed technique over the predictable and state of art image resolution enhancement techniques.
