Image spatial resolution enhancement using the wavelet transform is a quite classic topic in the field of image processing and there exist many algorithms, techniques and methods regarding wavelet and image resolution. Most of these approaches are based on the idea that the low resolution image is the approximation subband of a higher resolution image and try to estimate the unknown detail coefficients to rebuild the high resolution image. In this paper, we present a short review on the state-of-the-art techniques for wavelet based image resolution enhancement. We summarize them with enhancement ability in PSNR and give comments on their performance. The newness of this paper is that, through our review we have found some essential criteria and issues related to performance assessment of different resolution enhancement techniques. Our simulated results have proved the importance of these issues. Future directions for image resolution enhancement research are stated at the end.
