Video super-resolution method, program, and device

A non-transitory machine readable medium containing instructions for video super resolution that, when executed, direct one or more processors to:

• create image groups having different frame rates from an input video;
• perform motion estimation for each of the created image groups;
• select at least one image group having a frame rate based on an estimated motion amount;
• obtain a super-resolved image group by performing video super-resolution on the selected image group;
• and
• generate a high-resolution video by performing weighted averaging of the super-resolved image group.

A video super-resolution device comprising:

• a creating unit configured to create image groups having different frame rates from an input video;
• an estimating unit configured to perform motion estimation for each of the created image groups;
• a selecting unit configured to select at least one image group having a frame rate based on an estimated motion amount;
• and
• an averaging unit configured to generate a high-resolution video by performing weighted averaging of a super-resolved image group obtained by performing video super-resolution on the selected image group.
