Abstract

fetched live from OpenAlex

Recent advancements in the one-stream tracking framework have demonstrated the power of unified feature learning and relation modelling for robust visual object tracking. The methods under this framework might suffer from noisy attention scores in the process of extraction of the feature maps within the transformer blocks. This paper introduces a novel Learnable Laplacian Embedding Decomposition (LLED) module designed to enhance one-stream trackers by explicitly decomposing the learned feature embeddings into a set of Laplacian embeddings, each representing a different scale of structural information that works as a band-pass filter after each encoder block. This filter rejects attention scores corresponding to extremely low or high frequencies, effectively suppressing noise and background distractors while emphasizing features most relevant to the target object. Experimental results on multiple challenging benchmarks, including GOT-10k, UAV123, and OTB2015, demonstrate that LLED, which is enhanced by the proposed band-pass filtering, significantly improves the localization accuracy of state-of-the-art one-stream trackers while maintaining their real-time speed. This work highlights the importance of structural information and its interplay with attentional mechanisms for precise tracking and provides a novel approach for integrating it into the efficient one-stream paradigm.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
