Jagged edge reduction using kernel regression
First Claim
Patent Images
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.

Abstract
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.

detecting an edge in an image; dilating the detected edge of the image to include portions of the image adjacent to the detected edge in a dilated image region; selectively applying kernel regression to 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. - View Dependent Claims (7, 8, 9)

10. A computer-implemented method comprising:
-
detecting an edge in an image, including comparing the image to plural jagged edge configurations; selectively applying kernel regression to portions of the image based, at least in part, on the detection of the edge in the image corresponding to the jagged edge configurations; and outputting a corrected image. - View Dependent Claims (11, 12, 13, 14, 15)
