This paper explains and implements a fast image mosaic algorithm for unmanned aerial vehicle (UAV) sequence images. In this algorithm, feature points between images are matched using a modified Harris corner detection algorithm, and then an improved pyramid Lucas-Kanade optical flow algorithm and corner points matching authentication algorithm is used to achieve an effective match of the feature points...
Actions in real world applications typically take place in cluttered environments with large variations in the orientation and scale of the actor. We present an approach to simultaneously track and recognize known actions that is robust to such variations, starting from a person detection in the standing pose. In our approach we first render synthetic poses from multiple viewpoints using Mocap data...
