Abstract
The present invention relates to the fast multi-object detection and tracking system. According to the system of the present invention, only a few frames are to be detected and the other frames are split into different size of steady motion segments in a binary way, and then the system of the present invention can predicted accurately. The system can help to achieve high tracking speed with multi-persons in high-definition videos and gain high accuracy as well.
Claims23
A multi-object detection and tracking system, comprising:
- a) preprocess unit which is configured to select a plurality of first sampled frames to divide a sequence of images into frame cells;
- b) global object detector which is configured to perform object detection on the whole image of the first sampled frames, and give out global detection results;
- c) frame sampling unit which is configured to select at least one second sampled frame in a frame cell;
- d) local object detector which is configured to perform object detection on the region-of-interest of the second sampled frames, and output local detection results;
- e) data association unit which is configured to align the global detection results and the local detection results with existed trajectories by object similarity.
