摘要

为了进一步降低并行视频编码的功耗，本文提出了一种基于差分检测和基于Hilbert变换的工作量估计(HTWE)的编码系统。所提出的并行编码系统在不造成客观性能损失的情况下，可将并行编码的计算复杂度平均降低40%。对于具有频率和电压可扩展性的多核平台，可实现高达78%的功耗降低。

Low power parallel encoding system for video surveillance applications

In this paper, an encoding system is proposed to further reduce the power consumption in parallel video encoding based on difference detection and Hilbert transform based workload estimation (HTWE). The proposed parallel encoding system provides an average of 40% computational complexity reduction for parallel encoding without objective performance loss. For the multi-core platform with frequency and voltage scalability, up to 78% of power reduction can be achieved.
