- Abstract:
-
Due to the low spatial resolution of deep features extracted by pre-trained convolutional neural network, fast motion causes loss of spatial details of a moving object. This paper proposes a method to construct a siamese network for object tracking, so as to reduce the redundancy between the deep feature channels and the loss of high-level information. First, the VGG-16 convolutional neural network is trained offline to extract deep features and form the initial deep feature space. And then, the regional loss function is used to construct the feature and scale selection network. The feature is selected according to the gradient size of back propagation. Further, the selected features are spliced and integrated into the siamese network for matching tracking. By comparing OTB-2013, OTB-2015, VOT2016 and TempleColor benchmark datasets with other algorithms, it shows that the algorithm has preferable precision and robustness in the challenging scenarios such as fast motion and low resolution.
