Abstract—In recent years, a number of super-resolution
techniques have been proposed. Most of these techniques
construct a high resolution image by either combining several
low resolution images at sub-pixel misalignments or by learning
correspondences between low and high resolution image pairs.
In this paper we present a stochastic super-resolution method
for color textures from a single image. The proposed algorithm
takes advantage of the repetitive nature of textures and the
existence of several similar patches within the texture, as well as
the color-intensity correlation that often exist in natural images.
In the first step of the algorithm the intensity component is
interpolated. For each pixel, the missing value is chosen
according to a probability distribution constructed from a
measure of similarity to other patches in the texture as well as
from local features and patch color similarity. In the second
stage, the color components are interpolated in a similar
manner, using patches of the color channels as well as the
already interpolated intensity values. Our conclusion is that the
proposed approach outperforms presently available methods.
