Abstract

High-Definition (HD) videos often contain rich details as well as large homogeneous regions. To exploit such a property, Variable Block-size Transforms (VBT) should be in place so that transform block size can adapt to local activities. In this paper, we propose a 16× 16 Integer Cosine Transform (ICT) for HD video coding, which is simple and efficient. This 16×16 ICT is integrated into the AVS Zengqiang Profile and used adaptively as an alternative to the 8×8 ICT. Experimental results show that 16×16 transform can be a very efficient coding tool especially for HD video coding.
