Method and apparatus for performing single-image super-resolution

A method for performing super-resolution of a single image, comprising a step of generating a high-resolution version of an observed image by exploiting cross-scale self-similarity, wherein filters adapted for acting as up-scaling and analysis filters are used, and wherein the up-scaling and analysis filters are adaptively selected from among a plurality of filters with different roll-off factors.

An apparatus for performing super-resolution of single image, wherein a high-resolution version of an observed image is generated by exploiting cross-scale self-similarity, the apparatus comprising filters adapted for acting as up-scaling and analysis filters, wherein the apparatus comprises an adaptive selection unit for adaptively selecting the up-scaling and analysis filters, wherein the adaptive selection unit is adapted for adaptively selecting a filter from among a plurality of filters with different roll-off factors.

A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that when executed on a computer perform super-resolution of a single image, wherein a high-resolution version of an observed image is generated by exploiting cross-scale self-similarity, and wherein filters adapted for acting as up-scaling and analysis filters are used, and wherein the up-scaling and analysis filters are adaptively selected from among a plurality of filters with different roll-off factors.
