Abstract

In view of the defects of single feature and the problem of easy to miss when the target is fast changing, this paper proposed an adaptive feature fusion correlation filter tracking algorithm based on learning rate adjustment. The algorithm used complementary gradient features and color features to fuse the feature, and decided the weights of the features in the fusion feature in next frame by calculating the size of the filter response of each feature, so as to highlight the dominant features and make the target and background more discriminative. After extracting the target, it needed to update the filter. In order to avoid the situation that filter couldn't keep up with the change of the target, this paper introduced the learning rate adjustment mechanism, so that the update speed of the filter could be adjusted online with the appearance of the target. Therefore, compared with the similar feature fusion algorithm, the proposed algorithm is more accurate and efficient, and the robustness of the fast deformation target is stronger. The experiment shows that this algorithm is better than the existing correlation filter algorithms in accuracy and success rate, and has a certain application price.
