A VLSI Architecture for H.264/AVC Variable Block Size Motion Estimation

Dam. Minh Tung, Tran. Le Thang Dong
2015 Journal of Automation and Control Engineering  
In this paper, we propose an efficient VLSI architecture for variable block size motion estimation (VBSME) in H.264/AVC to reduce the hardware cost and latency.  ...  The proposed architecture adopts four modes (8x8, 8x16, 16x8 and 16x16 modes) instead of seven modes for VBSME specified in H.264/AVC.  ...  Therefore, it may limit the performance of the BMA for low bit rate video coding applications. Manuscript H.264/AVC remedies this limitation by using variable block size motion estimation (VBSME).  ...

Reducing Complexity of HEVC: A Deep Learning Approach

Mai Xu, Tianyi Li, Zulin Wang, Xin Deng, Ren Yang, Zhenyu Guan
2018 IEEE Transactions on Image Processing  
High Efficiency Video Coding (HEVC) significantly reduces bit-rates over the proceeding H.264 standard but at the expense of extremely high encoding complexity.  ...  In HEVC, the quad-tree partition of coding unit (CU) consumes a large proportion of the HEVC encoding complexity, due to the bruteforce search for rate-distortion optimization (RDO).  ...  As investigated by [2] , the encoding time of HEVC is higher than H.264/AVC by 253% on average, making it impractical for implementation in multimedia applications.  ...
