Effective Coding Unit Size Decision Based on Motion Homogeneity Classification for HEVC
conference contribution
posted on 2022-04-29, 09:51 authored by Thanuja MallikarachchiThanuja Mallikarachchi, Anil Fernando, Hemantha Kodikara ArachchiDetermining the best partitioning structure for a given Coding Tree Unit (CTU) is one of the most time consuming operations within the HEVC encoder. The brute force search through quad tree hierarchy has a significant impact on the encoding time especially on high definition (HD) videos. This paper presents a fast coding unit size decision-taking algorithm for inter prediction in HEVC. The proposed algorithm uses a motion homogeneity based classification approach utilizing RD cost as a feature vector. Simulation results show that the proposed algorithm achieves an average of 73.25% encoding time efficiency improvement with similar rate distortion performance compared to HEVC HM12.0 reference software.
