基于矩形分割的局部渲染技术在无线图像通信中的应用

为了提升无线图像通信中的图像渲染性能和减小数据的传输量,提出了一种优化算法,将基于矩形分割的局部渲染技术引入到无线图像通信中,以此减小每一帧的渲染区域和传输数据,以达到在节约CPU计算资源的同时,降低电量消耗和带宽依赖的目的。通过实验发现,该算法在图像相对变化较小的时候,最多能将渲染性能提升一倍,同时传输数据量和需要重新渲染的单个对象数量基本呈正比。实验结果证明,该算法有其适用范围,当图像较稳定的时候,平均能够提升30%以上计算性能,并减少50%以上的数据传输。

Application of Rectangle Incision Based on Part Render Technology in Wireless Picture Communication

For optimizing the performance of picture render and reduce the size of transfer data,this paper proposed an algorithm which can cut down the render area and the size of data to be transferred by part rendering.It is expected that this algoritms can save computational resources and reduce consumption of electricity and bandwidth at the same time.According to the experiment,this algorithm can optimize the render performance up to 100 percent when picture is not changing too much and the size of transferred data is directly proportional to the number of objects need to be re-rendered.This result proved that when the picture is relatively stable this algorithm can speed up the renderi performance by at least 30% and reduce 50% transferred data in the common cases.
