摘要：
In Scalable High Efficiency Video Coding (SHVC), inter-layer prediction efficiency may be degraded because much high frequency information can be removed during: 1) the down-sampling/up-sampling process and, 2) the base layer coding/quantization process. In this paper, we present a method to enhance the quality of the inter-layer reference (ILR) picture by combining the high frequency information from enhancement layer temporal reference pictures with the low frequency information from the up-sampled base layer picture. Experimental results show that on average 3.9% weighted BD-rate gain is achieved compared to SHM-2.0 under SHVC common test conditions.
