摘要
在TiDavinciDM6446DSP硬件基础上,结合Mean shift跟踪算法本身的特点,针对跟踪物体在大比例或相对时间长的阻挡,以及视频的采集、处理、传输过程可能出现的失真丢包现象,采用改进型的牛顿插值算法,确定目标接近真实位置的最优位置.插入改进后的算法具有很好的实时性和准确性.
For tracking objects in a large proportion or relative time length of the barrier, and video acquisition, processing, transmission may occur distortion loss phenomenon. Using the modified Newton interpolation algorithm, and combined with characteristics of Mean shift tracking algorithm to determine the target close to the true location of the optimal location, based on TiDavinciDM6446DSP hardware. Insertion of the improved algorithm has good accuracy and real-time performance.
