CrowdFlow
The TUB CrowdFlow is a synthetic dataset that contains 10 sequences showing 5 scenes. Each scene is rendered twice: with a static point of view and a dynamic camera to simulate drone/UAV based surveillance. The scenes are render using Unreal Engine at HD resolution (1280x720) at 25 fps, which is typical for current commercial CCTV surveillance systems. The total number of frames is 3200. Each sequence has the following ground-truth data: * Optical flow fields * Person trajectories (up to 1451) * Dense pixel trajectories Source: Optical Flow Dataset and Benchmark for Visual Crowd Analysis
