Abstract:

A novel supe-resolution method is proposed to construct a higher resolution image from a low resolution image using fractal coding. This super-resolution method utilizes a special type of orthogonal fractal coding method in which the fractal affine transform is determined by the range block mean and contrast scaling. The proposed non-adaptive fractal super-resolution procedure uses a fixed domain block and a fixed contrast scaling factor. Thus, no additional information must be stored for the fractal coding. Because the mean of each range block of the decoding series in the orthogonal fractal decoding is invariant, a higher resolution image consists of range blocks can be reconstructed from a low resolution image consisting of range block means. Experimental results are presented to show the impact of this method in terms of image quality and its computational requirements.
