Performance of different still picture interpolative coding schemes on block matching algorithm

Still picture coding techniques such as adaptive interpolative coding are always applied to intraframe image compression in video coding algorithms. Coding fidelity is always utilized in measuring the performance of still picture coding methods. In this paper, a popular motion estimation method known as the block matching algorithm (BMA) is adopted in reconstructing interframe images based on the contents of the intraframe images encoded with different still picture coding techniques. The compatibility of the still picture coding techniques can be reflected from the coding fidelities of interframe images. Experimental results show that adaptive interpolative coding with edge prediction technique has better compatibility with BMA and better visual quality is achieved
