A Cross-Domain Few-Shot Visual Object Tracker Based on Bidirectional Adversary Generation

Current deep-learning frameworks for object tracking based on transformers usually combine convolutional networks for feature learning. From the perspective of model performance, such network composition usually relies on a large number of labeled training samples, and the insufficient amount of data directly limits feature learning, represented by underfitting and instability of tracking results under specific data. A cross-domain few-shot object tracking framework based on a bidirectional adversary generation strategy is proposed. The object tracking model proposed in this article achieves few-shot tracking tasks in complex scenes by acquiring empirical knowledge from features learned from cross-sample domains. Specifically, we construct a multitask encoder for parallel-domain adaptation and few-shot feature learning using the adversarial mechanism to achieve bidirectional adaptive feature distribution alignment and then obtain the prediction information of the target. The algorithm obtains advanced results on OTB-100 and GOT-10k datasets, and multiple experiments show that the algorithm achieves advanced performance.
