运动估计and tracking are key activities in many computer vision applications, including activity recognition, traffic monitoring, automotive safety, and surveillance.

计算机视觉工具箱™ provides video tracking algorithms, such as continuously adaptive mean shift (CAMShift) and Kanade-Lucas-Tomasi (KLT). You can use these algorithms for tracking a single object or as building blocks in a more complex tracking system. The toolbox also provides a framework for multiple object tracking that includes卡尔曼过滤以及用于为轨道分配对象检测的匈牙利算法。

运动估计是一个过程,确定集团的运动吗ks between adjacent video frames. This toolbox includes motion estimation algorithms, such as光流，块匹配和模板匹配。这些算法创建了与整个图像，块，任意补丁或单个像素有关的运动向量。对于块和模板匹配，查找最佳匹配的评估指标包括MSE，MAD，MAXAD，SAD和SSD。
