Siamese network for real-time tracking with action-selection

Considering that most deep learning based trackers capture accurate locations for targets at the expense of consuming much time in training phrase, in this paper we present a new powerful tracker using the Siamese network which can be implemented with low computation resource. Our proposed tracker can track targets accurately by a fine-tuned model which is convenient to train. During the tracking, we apply a new sampling method that is independent of training called action-selection to conduct selective and flexible sampling step by step with a variable stride, by which we can get bounding boxes with varied aspect radio. By verifying its performance on online tracking benchmarks, it turns out that our tracker achieves higher accuracy than most traditional trackers. In addition, our tracker operates at frame-rates beyond real-time.
