Systems and methods for adaptive spatio-temporal filtering for image and video upscaling, denoising and sharpening

A computer system that is configured to perform adaptive spatio-temporal filtering, comprising:

• a processor;
• memory in electronic communication with the processor;
• instructions stored in the memory, the instructions being executable to:
• determine local motion vectors between a current video frame and other nearby video frames;
• determine local temporal confidence parameters;
• determine local spatial steering parameters;
• use the local motion vectors, the local temporal confidence parameters, and the local spatial steering parameters to adaptively determine spatio-temporal kernel weights;
• and
• use the spatio-temporal kernel weights to perform spatio-temporal filtering on input video data.

A computer-readable storage medium comprising instructions that, when executed by a processor, cause a computing device to:

• determine local motion vectors between a current video frame and other nearby video frames;
• determine local temporal confidence parameters;
• determine local spatial steering parameters;
• use the local motion vectors, the local temporal confidence parameters, and the local spatial steering parameters to adaptively determine spatio-temporal kernel weights;
• and
• use the spatio-temporal kernel weights to perform spatio-temporal filtering on input video data.
