H.264 Computation Resource Allocation in Multiple Priority Region of Interest
摘要
Abstract
The limitation of energy in battery powered devices is very challenging to apply H.264 to design a mobile sign language communication system.This paper therefore proposes a multiple priority Region of Interest(ROI) H.264 computation resource allocation scheme.In the system,the face,hands and background of sign language video is first detected with a fast algorithm.Then several coding parameters which allow the encoder to allocate computational resources differently are adaptively adjusted at the Macroblock(MB) level according to the relative priority of each MB.As a result,it keeps fine quality in face and hands,greatly reduces the computational complexity and prolongs the battery life.关键词
