| 摘 要： | 为降低序贯相似性检测算法(SSDA)的计算量,提出了一种双阈值快速SSDA算法(DTSSDA)。DTSSDA增加了误差累积速度阈值,当误差累积速度超过速度阈值时可提前终止本次匹配计算,而速度阈值可利用帧间相关性信息自动地选取。另外算法中还引入了积分图的概念并采用了从粗到精的搜索策略。实验表明DTSSDA能在保证匹配精度基本不变的前提下使单帧计算量大幅减少,因此更适合于实时目标跟踪。

| Abstract: | In order to reduce the computational cost of sequence similarity detection algorithm (SSDA),a fast SSDA with double hresholds(DTSSDA)was proposed in this paper.DTSSDA introduces another threshold related with error-increasing-speed (EIS),when EIS of a reference region exceeds the threshold,operations cease for the region.Threshold of EIS can be determined daptively according to correlation of inter-frame.Integral image was introduced in and search strategy of rough to fine is adopted n the algorithm.Experim... |
