利用C++实现的KLT跟踪算法，通过GPU提高算法效率。

基于GPU的klt跟踪算法，现在比较流行的基于光流分析的视频跟踪算法-GPU-based klt tracking algorithm, is now more popular optical flow-based analysis of video tracking algorithm

在gpu上运行的klt算法，可以实现角点检测与跟踪-In the GPU running on KLT algorithm, can achieve corner detection and tracking

This library implements the KLT Tracking algorithm [2004] for Feature Tracking in Video useful in computer vision tasks like object recognition, image indexing, tracking and structure from motion. This implementation uses programmable Graphics Hardwa
