Image Processing System and Image Processing Method |
摘要 |
Provided is an image processing device that can bring about the sufficient resemblance between an original image and a restored image obtained corresponding to a low resolution input image. The image processing device includes a means that uses a dictionary for storing data associating deteriorated patches which are from a deteriorated image formed by deteriorating a prescribed image, and restoration patches which are from the prescribed image, and calculates, as a degree-of-similarity between plural input patches generated by dividing an input image and the deteriorated patches, a weighted degree-of-similarity between weighted deteriorated patches and weighted input patches, in which forms of the deteriorated patches and the input patches are reconfigured using a patch weight which is continuous weighting; a means that selects, on the basis of the weighted degree-of-similarity, a restoration patch for each input patch; and a means that combines the restoration patches to generate a restored image. |

1. An image processing device, comprising:
a degree-of-similarity calculation unit which uses a dictionary for storing data of plural pairs associating deteriorated patches which are patches from a deteriorated image formed by deteriorating a prescribed image, and restoration patches which are patches from said prescribed image, and calculating, as a degree of similarity between plural input patches generated by dividing an input image which is input and said deteriorated patches, a weighted degree-of-similarity which is a degree-of-similarity between weighted deteriorated patches and weighted input patches in which forms of said deteriorated patches and said input patches are reconfigured using a patch weight which is continuous weight; a selection unit which selects, on the basis of said weighted degree-of-similarity, a restoration patch for each input patch; and a combination unit which combines said restoration patches, each of which is selected for each input patch, to generate a restored image. |
