Problems solved by technology

[0010] However, although 3D video coding adopts HEVC's intra prediction and depth model mode (DMM) technology, the direct wedge partition mode in the depth model mode brings unnecessary complexity when compressing the depth map

Abstract

The invention provides a wedge-shaped block intra-frame prediction method based on depth images. In one embodiment, a method for determining an optimal intra-frame prediction mode in high efficiency video coding (HEVC) comprises the following steps of during the direct wedge-shaped partitioning of four depth model modes, determining a wedge-shaped block form subset corresponding to a previously determined SATD (Sum of Absolute Transformed Difference) optimal mode from a wedge-shaped block form set having the same size with each prediction unit; and for each wedge-shaped block form in each determined wedge-shaped block form subset having the same size with each prediction unit, determining the optimal wedge-shaped block form as a candidate mode for determining the final optimal intra-frame prediction mode.
