Local self-similarity as a dense stereo correspondence measure for themal-visible video registration
Bibliographic record
Abstract
The robustness of Mutual Information (MI), the most used multimodal dense stereo correspondence measure, is restricted by the size of the matching windows. However, obtaining the appropriately sized MI windows for matching thermal-visible pair of images of multiple people with various poses, clothes, distances to cameras, and different levels of occlusions is quite challenging. In this paper, we propose local self-similarity (LSS) as a multimodal dense stereo correspondence measure. We integrated LSS as a similarity metric with a disparity voting registration method to demonstrate the suitability of LSS for a visible-thermal stereo registration method. We have analyzed comparatively LSS and MI as multimodal correspondence measures and discussed LSS advantages compared to MI. We have also tested our LSS-based registration method in several indoor videos of multiple people and shown that our registration method outperforms the most recent MI-based registration method in the state-of-the-art.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
