Abstract : "One of the most important and challenging research topics in the area of computer vision is visual object tracking, which is relevant to many real-world applications. Recently, discriminative correlation filters (DCF) have been demonstrated to overcome the problems in visual object tracking efficiently. So far, only single-resolution feature maps have been utilized in DCF. Owing to this limitation, the potential of DCF has not been exploited. Moreover, convolutional features have demonstrated a better performance for visual tracking than histogram of oriented gradients (HOG) features and color features. Based on these facts, in this paper, we propose collaborative learning based on multi-resolution feature maps for DCF, employing convolutional features. Further, the confidence score, which represents the location of the target object, is selected from various candidates based on certain rules. In addition, the continuous filters are trained to handle the variations of appearance of the target. The extensive experimental results obtained using VOT2015 and OTB-100 benchmark datasets show that the proposed algorithm performs favorably against state-of-the-art tracking algorithms."
