ABSTRACT:
A maximum a posteriori (MAP) filter is applied as a loop filter during encode/decode processing to generate filtered data used to encode/decode other data. In one embodiment, the MAP filter is applied iteratively to a decoded frame to generate the resulting filtered frame. When applied as a loop filter, the filtered frame is used to generate reference data used to encode or decode one or more other video frames.
