Tracking With Saliency Region Transformer
Summary
We introduce SRTrack, a novel two-stage visual tracker that efficiently handles redundant information. By employing an attention scaling factor, SRTrack achieves state-of-the-art accuracy and speed in visual tracking tasks.
Area of Science:
- Computer Vision
- Artificial Intelligence
Background:
- Transformers have advanced visual tracking but often suffer from decreased speed with increased model capacity.
- Massively redundant information in tracking sequences poses a challenge for efficient and accurate visual tracking.
Purpose of the Study:
- To develop an efficient and accurate visual tracker that addresses the speed-accuracy trade-off in Transformer-based models.
- To mitigate feature inconsistencies arising from the two-stage design in visual tracking.
Main Methods:
- Proposed the Saliency Region Tracker (SRTrack), a heuristic two-stage tracker with a lightweight initial stage and a saliency-based discriminative stage.
- Introduced an attention scaling factor to enhance model robustness and address feature extrapolation issues between training and inference.
Main Results:
- SRTrack achieved a state-of-the-art Area Under Curve (AUC) of 0.699 on the LaSOT benchmark.
- The tracker demonstrated high efficiency, running at 61 Frames Per Second (FPS) on LaSOT.
- Experiments on large benchmarks confirmed SRTrack's superior efficiency and accuracy.
Conclusions:
- SRTrack effectively balances accuracy and speed in visual tracking, outperforming existing methods.
- The proposed attention scaling factor improves model robustness and performance, making it suitable for challenging tracking scenarios.
