Adaptive Inter-Layer Prediction for Intra Texture on H.264 Scalable Video Coding

H.264 기반 스케일러블 비디오 부호화에서 인트라 블럭에 대한 적응적인 계층간 예측 연구

In the scalable extension of H.264/AVC, spatial scalability is provided residual information as encoding layered spatial resolution between layers. We use the inter-layer prediction to remove this redundancy. In the inter-layer prediction, as the prediction we can use the signal that is the upsampled signal of the lower resolution layer. In this case, coding efficiency can be different from optimal prediction by kinds of interpolation filter. This paper indicates technique to choose the interpolation filter and to enhance coding efficiency for finding more correct prediction in intra macroblock.
