Abstract
An algorithm for single image super-resolution based on example-based super-resolution and example-based texture synthesis is proposed. While many other techniques for single image super-resolution are mainly effective on edges, the proposed algorithm enhances both edges and texture detail. The algorithm does not use an additional example database as it uses self-examples to synthesize new detail and texture, assuming that images contain a sufficient amount of self-similarity. The texture synthesis component of the algorithm enables the re-synthesis of texture at the output resolution to achieve super-resolution. The algorithm aims to create plausible, visually pleasing detail rather than reconstructing the true high-resolution image. Experimental results for natural images confirm the algorithms ability to create visually pleasing results, but also indicate that its performance is highly content dependent. Future efforts will be aimed at improving the robustness of the method.
