SAMPLE ADAPTIVE OFFSET FOR HIGH EFFICIENCY VIDEO CODING

摘要

Disclosed is sample adaptive offset (SAO) of high efficiency video coding (HEVC). The SAO of HEVC comprises: a control module configured to output a control signal; a memory module configured to read pixel information from an external memory that stores information on the largest coding unit and transmit the pixel information to a processing module, in response to the control signal; and the processing module configured to classify the pixel information into edge offset and band offset in response to the control signal, determine and output optimal offset and an optimal sample adaptive offset parameter, and compensate for a restoration image using a sample adaptive offset parameter. Therefore, it is possible to reduce operation time and computational complexity.
