- Abstract:
-
The regularization filter defines the regularization term in advance, but it can not suppress the learning of non-target region in real time. Aiming at this shortcoming, a new adaptive spatiotemporal regularization method is proposed to improve robustness of the algorithm to adapt to appearance change in the process of target tracking. The method firstly introduces the spatial local response variation into the objective function, so that the filter can focus on the trusted part of the learning object, obtaining the response model. Then, the update rate of the filter is determined based on the change of global response. Finally, the convolutional neural network is introduced for deep feature extraction. In order to reduce the storage capacity of high-dimensional data, the principal component analysis algorithm is employed to reduce dimension, which not only retains the main features, but also speeds up the calculation. Comparing with the spatial-temporal regularized correlation filtering algorithms, the average accuracy and success rate of data sets OTB2013 and OTB2015 are respectively increased by 4.7% and 12.7%. A large number of experiments show that the algorithm basically meets the real-time requirements in complex background, object occlusion, fast motion and other scenes.
