Object Tracking Combined with Attention and Feature Fusion
The full-convolutional Siamese network solves the problem of object tracking through similarity learning
and the algorithm has received more and more attention. In order to extract more discriminative object features and improve the accuracy and robustness of tracking
an object tracking model combining attention mechanism and feature fusion is proposed. Firstly
the first frame and the previous frame of the current frame are combined as target templates
and the features from multiple convolution layers of the target templates and the current frame are extracted by using the shared feature extraction network. Furthermore
for the multi-layer convolution features of the target templates
the channel attention mechanism is adopted to improve the discriminative power of the template features. Finally
the features of the target templates are cross-correlated with the features of the current frame to obtain response map
thereby obtaining the position and scale of the predicted object in the current frame. The final experimental results show that compared with several advanced tracking models
the proposed object tracking model achieves relatively competitive performance.
