Method and Apparatus for Intra Mode Coding

摘要

A method and apparatus of predictive Intra coding of a block are disclosed. In one embodiment according to the present invention, a set of Intra prediction modes is determined, and predictive Intra coding is applied to a prediction unit (PU) of an image based on one or more neighboring PUs according to a current Intra prediction mode. The current Intra prediction mode is selected from the set of Intra prediction modes and the current Intra prediction mode is predicted using most probable modes (MPMs) and remaining modes. A number of the remaining modes is kept as a power of 2. For example, the 32 remaining modes can be represented using 5-bit fixed length codes.
