Fast multi-object detection and tracking system
First Claim
Patent Images
1. 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.

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.
