Computer-implemented method, apparatus, and computer-program product

An apparatus, comprising:

• one or more memory;
• and
• one or more processors;
• wherein the one or more memory and the one or more processors are connected with each other;
• and
• the one or more memory stores computer-executable instructions for controlling the one or more processors to:
• input a low-resolution image and a plurality of high-resolution images into a feature extractor, the low-resolution image and the plurality of high-resolution images comprising images of a target object;
• obtain, by the feature extractor, feature maps of the low-resolution image and the plurality of high-resolution images;
• compare similarities between the feature maps of the low-resolution image and the plurality of high-resolution images;
• obtain selected feature maps of one or more selected high-resolution images of the plurality of high-resolution images most similar to the low-resolution image;
• input the selected feature maps into a generator to output a repair image;
• enhance the low-resolution image using a pre-processing image enhancing process to generate an enhanced image;
• and
• morph the repair image with the enhanced image.

A computer-program product comprising a non-transitory tangible computer-readable medium having computer-readable instructions thereon, the computer-readable instructions being executable by a processor to cause the processor to perform:

• inputting a low-resolution image and a plurality of high-resolution images into a feature extractor, the low-resolution image and the plurality of high-resolution images comprising images of a target object;
• obtaining, by the feature extractor, feature maps of the low-resolution image and the plurality of high-resolution images;
• comparing similarities between the feature maps of the low-resolution image and the plurality of high-resolution images;
• obtaining selected feature maps of one or more selected high-resolution images of the plurality of high-resolution images most similar to the low-resolution image;
• inputting the selected feature maps into a generator to output a repair image;
• enhancing the low-resolution image using a pre-processing image enhancing process to generate an enhanced image;
• and
• morphing the repair image with the enhanced image.
