Abstract
Systems and methods for improving operation of a video encoding pipeline, which includes a sample adaptive offset block that selects an offset sample from image data corresponding with a coding unit; determines edge offset parameters including a first mapping of an edge classification to an edge offset value and band offset parameters including a second mapping of a band classification to a band offset value based at least in part on analysis of the offset sample; and determines sample adaptive offset parameters based at least in part on a first rate-distortion cost associated with the edge offset parameters and a second rate-distortion cost associated with the band offset parameters. Additionally, a decoding device may apply offsets to decoded image data corresponding with the coding unit based at least in part on the sample adaptive offset parameters.
