Method and Apparatus for Image and Video Coding Using Hierarchical Sample Adaptive Band Offset

Abstract:

A method and apparatus for image coding using hierarchical sample adaptive band offset. The method includes decoding a signal of a portion of an image, determining a band offset type and offset of a portion of the image, utilizing the band offset type and offset to determine a sub-band, and reconstructing a pixel value according to the determined offset value.
