| 摘要 | The H.264/MPEG-4 (Advanced Video Coding) AVC video coding includes a multidirectional spatial prediction method to reduce spatial redundancy by using neighboring samples as a prediction for the samples in a block of data to be encoded. The main goal of the intra prediction is to achieve better compression efficiency. For finding the optimal prediction modes, H.264/MPEG-4 AVC adopts the full search algorithm in the standard. The high computation complexity of the full search algorithm makes the encoding of H.264/MPEG-4 AVC to be difficult to meet real time applications. In this work, we proposed a Fast Intra Prediction Mode Decision Algorithm (FIPMDA) for 4 4 intra blocks, which is based on the partially sampling prediction and symmetry of the adjacent angle modes, to reduce the computational time and low complexity of the 4 4 block intra-prediction. Experimental results show that the proposed method can reduce the encoder time of the intra prediction by more than 60% while maintaining similar video bit rate and quality. |
