AI Technical Summary

Technical Problem

When processing complex motion videos, existing frame rate up-conversion methods are prone to motion estimation errors, resulting in unreliable interpolation quality and artifacts, which affect the video viewing experience.

Method used

Through interpolation quality reliability prediction, the interpolation quality is judged using reliability metrics. When the reliability threshold condition is met, motion compensation interpolation is performed. Otherwise, a fallback interpolation mechanism is adopted, including repeating or averaging reference frame pixels, to reduce the occurrence of artifacts.

Benefits of technology

Improves video display quality, reduces artifacts in complex motion videos, and enhances user experience.

Abstract

The present disclosure provides systems and methods for frame rate up-conversion of video data. According to one aspect of the present disclosure, a computer-implemented method for performing frame rate up-conversion on video data comprising a sequence of image frames is provided. The method may include performing, by a video processor, an interpolation quality reliability prediction for a target image level based on a reliability metric. In response to the interpolation quality reliability prediction satisfying a first reliability threshold condition associated with a first reliability threshold, the method may include performing, by the video processor, motion compensated interpolation at the target image level. In response to the interpolation quality reliability prediction not satisfying the first reliability threshold condition, the method may include performing, by the video processor, fallback interpolation at the target image level or performing a new interpolation quality reliability prediction for a new image level lower than the target image level.
