End-to-End Material Prompt Tracking (E2E-MPT) is a framework that integrates hyperspectral unmixing and object tracking, jointly optimizing them to learn target-discriminative material representations. This approach consistently achieved state-of-the-art performance on three hyperspectral tracking benchmarks, improving distance precision by up to 6.6% and AUC metrics by up to 4.5% over strong baselines.
Key insights
- Jointly optimizing hyperspectral unmixing with object tracking significantly enhances tracking robustness and accuracy by learning material representations directly relevant to target discrimination.
- Decomposing material abundance maps into complementary low- and high-frequency components, and fusing them asymmetrically, effectively leverages both global material responses and local, fine-grained variations for robust tracking.
- A novel target-oriented unmixing loss function is crucial for aligning the unmixing process with the tracking task, enabling the generation of material prompts that are highly discriminative for the target while suppressing background noise.
