基于时空注意力机制的目标跟踪算法

Object tracking technology is widely used in intelligent monitoring,human-computer interaction,unmanned driving and many other fields.In recent years,many efficient tracking methods are proposed.However,object tracking methods still face great challenges in the complex scenario such as occlusion,illumination variations,background clutter,which leads to tracking failure.To solve the above mentioned problems,in this paper,an effective object tracking algorithm is proposed based on temporal-spatial attention mechanism.Firstly,we utilize the Siamese network architecture to improve the discriminative ability of object features.Then,the improved channel attention module and spatial attention module are introduced into the Siamese network,which imposes different weights on the features of different channels and spatial positions and focuses on the features that are beneficial to object tracking in spatial and channel positions.In addition,an efficient online object template updating mechanism is developed,which combines the features of the first frame and the features of the following frames with high confidence to reduce the risk of the object drift.Finally,the proposed tracking algorithm is tested on OTB2013 and OTB2015 benchmarks.Experimental results show that the performance of the proposed algorithm improves by 6.3% compared with the current mainstream tracking algorithms.
