A Fast Algorithm of Intra Mode Decision Based on H.264/AVC
Hongcheng Wang · Microcomputer applications · 2006
The video coding standard H. 264/AVC uses intra and inter mode decisions to improve rate distortion performance. However, thismulti-mode selection and exhaustive search increase the complexity of the codinggreatly. In our proposed fast intra prediction algorithm, we use the directional information of Intra-16x16 to cut down the amount of Intra 4x4 modes which is selected. Experimental results show that the proposed algorithm enhances the speed of intra coding significantly with only negligible coding efficiency loss.
