Real-time visual tracking via robust Kernelized Correlation Filter
Bibliographic record
Abstract
There has been an increasing interest in the use of correlation filters for visual object tracking due to their impressive tracking performance. However, existing correlation filter based tracking methods, such as Struck and Kernelized Correlation Filter (KCF), cannot always solve tracking problems in complicated conditions such as heavy occlusion and aggressive motion. In this paper, we proposed a real-time visual tracker via a robust KCF. We start by implementing a search window alignment, based on a motion model with uncertainty, which increases the tracking accuracy for fast moving targets and reduces the padding value to accelerate tracking speed. Next, we establish a combined confidence measurement including occlusion information, which is utilized for robust updating. Then we apply an adaptive Kalman filter to improve the tracking accuracy. Qualitative and quantitative experimental results show that the proposed algorithm outperforms the state-of-the-art methods such as KCF and Struck.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
