Among the coding methods, intra coding is a very important one. The prediction accuracy of intra coding is the key to performance enhancement. This thesis presents a high efficiency video coding method using predictive texture synthesis. First, the proposed method selects two predictive blocks with different prediction directions and synthesizes these two prediction blocks. The proposed method then employs two core methods (combined mode selection method and weight recover technique) to enhance coding performance of intra coding. The combined mode selection method reduces the bits required to suggest which two modes are selected in the decoder and the computational complexity of selecting the two modes; meanwhile, the weight recover technique saves the bits required for weights in the decoder. Experimental results show that the proposed method improves the coding performance of intra prediction.
