Jagged edge reduction using kernel regression

摘要

An image decoder includes a base layer to decode at least a portion of an encoded video stream into a first image having a first image format. The image decoder can generate a color space prediction by scaling a color space of the first image from the first image format into a color space corresponding to a second image format. The image decoder includes an enhancement layer to decode the encoded video stream to generate a second image in the second image format based, at least in part, on the color space prediction.

1. A computer-implemented method comprising:
detecting edges in an image, including portions of the image that correspond to a jagged edge configuration; selectively applying kernel regression to portions of the image that correspond to the jagged edge configuration; and outputting a corrected image.
