摘要
针对视频图像运动目标检测算法数据量多、处理速度慢的缺点,提出了对运动目标检测算法的优化方法,使用基于TMS320C64X系列DSP的程序优化方法对运动目标检测代码进行优化,采用了编译器选项、内联函数与宏定义、查找表、软件流水等优化方法,最后综合分析了相关优化方法对于时间性能的改进情况,实验结果证明了优化方法的有效性。
Based on the characteristics of a lot image data and low processing speed in video-based moving object detection methods, some programming optimization skills for fast algorithms are summarized on TMS320C64x platform, including using compiler options, using intrinsic and macro definition, using look-up table, using loop optimizing, etc. Then the time per-formance of related optimization skills is analysed. Experimental results indicate the validation of the optimization methods.
