Aiming at the problem of tracking drift or loss caused by the occlusion and the out-of-view of the target in long-term tracking, this paper proposes a new deep, long-term tracking algorithm based on MDNet (LT-MDNet). First, an improved shrinkage loss function is introduced to solve the problem of the positive-negative class imbalance in the model training. Second, a high confidence retention sample pool is designed to retain the valid and highest confidence results of each frame during online tracking and to replace the lowest confidence retention samples when the pool is full. Finally, when the model detects a tracking failure or when the continuous tracking frame number reaches a specific threshold, the reserved sample pool is used for online training to update the model to make the model robust and efficient in dealing with long-term tracking. Experimental results show that LT-MDNet is highly competitive in its tracking accuracy and success rate and maintains excellent tracking performance and reliability in the case of target occlusion and out-of-view.
