Abstract

In the field of computer vision, object tracking is a hot research topic. At present, the coordinate box of most algorithms is vertical box. However, in practical application, the frame selection area of the object is expanded due to the rotation of the object, which makes it impossible to obtain the real motion angle of the object. To solve this problem, this paper proposes a Siamese network tracking algorithm (SiamRotate) based on rotation box reinforcement learning. In order to predict the rotation Angle of the object, firstly, we process the VOT2013 and VOT2014 datasets to increase the angle richness and used the processed datasets to train the angle decision-making network through the combination of supervised training and reinforcement learning. Based on the SiamRPN network, the tracking network obtains the feature response through the deep cross-correlation operation of the feature map of the two branches through SiamRPN, and then processes the feature response map through the angle decision network to predict the object rotation angle. The performance indexes of the proposed method reached 0.62(A), 0.21(R), 0.425(EAO) on VOT2016, and 0.61(A), 0.27(R), 0.399(EAO) on VOT2018, and the tracking speed reaches 138fps. Finally, comparative experiments show that the algorithm has good performance in speed and accuracy.
