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.
Claims20
A method comprising:
- determining, by an image processing system, directional gradients corresponding to pixels in an image;
- generating, by the image processing system, a linear predictor and a quadratic predictor from the directional gradients;
- and
- modifying, by the image processing system, the pixels in the image with kernel regression utilizing the linear predictor and the quadratic predictor.

An apparatus comprising:
- an image processing system configured to generate directional gradients corresponding to pixels in an image, generate a linear predictor and a quadratic predictor from the directional gradients, and modify the pixels in the image with kernel regression utilizing the linear predictor and the quadratic predictor.
A method comprising:
- detecting edges in an image;
- and
- selectively applying kernel regression to portions of the image based, at least in part, on the detection of the edges in the image.
