Title:
METHOD AND APPARATUS OF INTRA-INTER PREDICTION MODE FOR VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2018/224004
Kind Code:
A1
Abstract:
Method and apparatus of video coding are disclosed. According to the method, a boundary region in the current block is determined. For each pixel in the boundary region, an Intra predictor and an Inter predictor care derived. An Intra-Inter predictor is generated by blending the Intra predictor and the Inter predictor. Pixels in the boundary region of the current block are encoded or decoded using the Intra-Inter predictor. For the remaining pixels in the current block not belonging to the boundary region, the pixels are encoded or decoded using the Inter predictor or the Intra predictor. In another method, the Intra-Inter prediction process is implemented by scaling the sum of the Intra weighting factor and the Inter weighting factor is scaled to a power-of-2 number to avoid the need for the division operation. In yet another method, the Intra-Inter prediction is applied depending on the current block size.
