Abstract
Obtaining a restored frame from a degraded frame includes obtaining, for a pixel of the degraded frame, magnitude features based on a first window centered at the pixel. A cardinality N of the magnitude features is at least 1. The magnitude features are used to obtain a pixel-adaptive filter. The pixel-adaptive filter is applied to the pixel to obtain a pixel of the restored frame.
Claims20
A method for obtaining a restored frame from a degraded frame, comprising:
- obtaining, for a pixel of the degraded frame, magnitude features based on a first window centered at the pixel, wherein a cardinality N of the magnitude features is at least 1;
- using the magnitude features to obtain a pixel-adaptive filter;
- and
- applying the pixel-adaptive filter to the pixel to obtain a pixel of the restored frame.

A method, comprising:
- obtaining a filter bank comprising filters;
- obtaining, for pixels of a degraded frame, respective sets of combining scalars for combining the filters of the filter bank:
- obtaining, for the pixels of the degraded frame, respective pixel-specific filters by combining the filters of the filter bank using the respective sets of combining scalars;
- and
- obtaining a restored frame by filtering the pixels of the degraded frame using the respective pixel-specific filters.
