visualc++和opencv实现。点跟踪。改进的Lucas-Kanade光流算法，检测视频运动目标。鼠标点击目标点，视频跟踪。-Point tracking. Improved Lucas-Kanade optical flow algorithm, video motion detection target. Click on the target point, video tracking.

在计算机视觉中，Lucas–Kanade光流算法是一种两帧差分的光流估计算法。它由Bruce D. Lucas 和 Takeo Kanade提出。(In computer vision, the Lucas - Kanade optical flow algorithm is a two frame differential optical flow estimation algorithm. It is proposed by Bruce D. Lucas and Takeo Kanade.)
