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 method of context-adaptive pixel processing comprising:
classifying, via an electronic device, 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 the classification of other pixels near the particular pixel; and generating a content indicator for the frame based at least in part upon the weighting-value of at least one pixel of the first plurality of pixels.
