Feature Reduction on Fuzzy SVM-Based Coding Unit Decision in HEVC

Abstract

This paper proposes a feature reduction approach on a fuzzy SVM-based Coding Unit (CU) size decision method in a recent video encoding standard, High Efficiency Video Coding (HEVC). The proposed feature reduction approach with Rate Control (RC) can reduce computational complexity by eliminating some correlated features of a fuzzy SVM-based CU size decision method under a similar coding efficiency. According to the empirical results, our approach can achieve up to 3% of Time Saving (TS) under the same RD performance over a fuzzy SVM-based approach.
