Infrared Multi-Pedestrian Tracking in Vertical View via Siamese Convolution Network

Abstract

Target tracking has become one of the research hotspots in the field of computer vision in recent years. In this paper, a new intelligent algorithm of infrared multi-pedestrian tracking in vertical view is proposed. In the algorithm, the pedestrians in the infrared image can be quickly detected and located with the method of the Faster Regions with CNN features (RCNN) and then are tracked with the improved Siamese network. The tracking method based on Siamese network transforms the tracking problem into a similarity verification problem and evaluates the similarity score between new frame feature and target frame feature by convolution network. The candidate region with the highest score is considered as the current position of the target. In this paper, the Siamese network is combined with Faster RCNN for multi-pedestrian tracking. In addition, the tracking results of adjacent frames are introduced into the similarity evaluation of current frames to improve the tracking accuracy when the pedestrian posture changes. The experimental results show that the algorithm has good robustness and tracking result and achieves competitive performance.
