Content-adaptive pixel processing systems, methods and apparatus

摘要

Embodiments include methods and systems for context-adaptive pixel processing based, in part, on a respective weighting-value for each pixel or a group of pixels. The weighting-values provide an indication as to which pixels are more pertinent to pixel processing computations. Computational resources and effort can be focused on pixels with higher weights, which are generally more pertinent for certain pixel processing determinations.

主权项

1. A computer-implemented method of context-adaptive pixel processing comprising:
classifying, via an electronic device on a pixel by pixel basis, a first plurality of pixels of a frame into one class of a plurality of classes; determining a respective weighting-value for each of the first plurality of pixels of the frame, wherein each weighting-value is based at least in part on a comparison of a classification of a particular one of the pixels with a classification of other pixels near the particular one of the pixels; and generating context-adaptive pixel weighting values for processing the frame by smoothing one or more of the weighting-values.
