Abstract
En 中文
Versatile Video Coding (VVC/H.266), the latest video standard, introduces multiple new coding techniques. Among these, Multiple Transform Selection (MTS) aims to enhance transform coding efficiency in the encoder. However, MTS increases coding complexity. This paper presents a new lightweight AI-based method to streamline MTS in VVC using machine learning, specifically the Random Forest algorithm. Our method simplifies transform selection in the VVC module, replacing the original complex process. Experimental results using VVC reference software VTM-14 in random access configuration at QP 32 show that our algorithm reduces transform coding time by 39.44% and overall encoder time by 9%, with only a 1.6% increase in bitrate compared to the standard method.
