LIU Enhan, ZHANG Rui, ZHAO Shuo, et al. Infrared pedestrian target tracking method based on video prediction[J]. 2020, 52(10): 192-200.DOI: 10.11918/201910048.
infrared video is easily affected by the surrounding environment. In infrared pedestrian tracking
the appearance contour and gray distribution of the pedestrian target often have great changes
which lead to the difficulty of tracking. To solve this problem
this paper proposes a VPSiamRPN (Video prediction with Siamese Region Proposal Network) infrared pedestrian target tracking system. Aiming at the factors that seriously affect the performance of infrared pedestrian tracking (such as target deformation
target occlusion
and background clutter)
the image prediction function of PredNet (Deep Predictive Coding Networks for Video Prediction and Unsupervised) was designed and applied to SiamRPN (Siamese Region Proposal Network) to improve the similarity between the tracking template and the detected target
so as to improve the tracking ability to the infrared pedestrian target. Nine comparative experiments were carried out by changing the number of layers of the network
the number of target images and frames used for prediction
and the tracking strategy of the network. On PTB-TIR dataset
experimental results show that the success plots and precision of theinfrared target recognition in thermal crossover
intensity change
occlusion
scale variation
and other attributes were much higher than those of SiamRPN
indicating good performance of infrared pedestrian tracking
which will have broad application prospects in this field.
