Abstract Visual object tracking is one of the challenging tasks in computer vision. Among tracking tasks, accurately state estimation is the main challenge. Most current methods simply adopt multi-scale searches or anchors to estimate the state, which need many hyper-parameters and complex calculations. To face this challenge, we propose an anchor-free tracking framework based on Siamese network. The proposed framework consists of template features guided Siamese subnetwork and keypoints detection subnetwork. We take simplified hourglass network as backbone in Siamese subnetwork to improve the tracking efficiency and the prediction of corners around target instead of the prediction of target in keypoints detection subnetwork. We experiment our approach on OTB-2015 and VOT-2016, and our approach acquire the best precision of 0.841 on OTB-2015 and runs at 39 FPS.
