Novel Dataset for Fine-grained Abnormal Behavior Understanding in Crowd 数据库：https://github.com/hosseinm/med
2 Proposed Dataset
The introduced dataset consists of 31 video sequences in total or as about 44,000 normal and abnormal video clips. The videos were recorded as 30 frames per second using a fixed video camera elevated at a height, overlooking individual walkways and the video resolution is 554 * 235. The crowd density in the scene was changeable, ranging from sparse to very crowded.
3 Proposed Benchmark
Dense trajectories [25,26](SeeFig. 4)which have shown to be efficient for action recognition are applied as first method on our dataset.
As second benchmark, we use Histogramof OrientedTracklet (HOT) [14, 15,16] descriptor, which is suitable for the task of abnormality detection
