Method of single image super-resolution enhancement based on fractal coding
He Si-hua, Wu Zhen · 2013
According to the local characteristics of image similarity and transitivity, self-similarity and scale invariance characteristic of fractal characteristics, use fractal coding as the characteristic of similarity evaluation criteria, search internal image blocks and use the low resolution image analogy fusion in a single image to reconstruct a high resolution image information blocks, implement super-resolution enhancement based on fractal coding. The experimental results show that the fractal coding method can keep the image details better, the reconstruction error is smaller, is better than the bilinear interpolation and bicubic interpolation method.
