Abstract
A system and method for coding video in which deblocking artifacts are reduced by using modified filtering that is based, at least in part on pixel intensity associated with a coding unit, such that filtering levels are increased as pixel intensity increases. In some embodiments, an offset value or indicator of an offset value for parameters associated with deblocking filter parameters can be associated with a filtering level that is based at least in part on an intensity value.
Claims12
A method of encoding video comprising:
- determining a coding unit;
- determining intensity information of pixels associated with a boundary of said coding unit;
- applying deblocking filtering to said coding unit prior to encoding, based at least in part on intensity information associated with said coding unit;
- and
- encoding said coding unit for transmission.
