Abstract

fetched live from OpenAlex

This paper proposes a new approach in structured light correspondence to alleviate the camera-projector synchronization problem. Until now, great care was required to make sure that each camera image was corresponding exactly the correct pattern in the sequence. This was difficult to achieve with low-cost hardware or large size installations. In our method, the projector sends a constant video loop of a selected number of unstructured light patterns at a high frame rate (30 to 60 fps for common hardware), which are captured by a camera without any form of synchronization. The only constraint to satisfy is that the camera and projector frame rates are known. The matching process not only recovers the correct pattern sequence, but is impervious to partial exposures of consecutive patterns as well as rolling shutter effects.

Full frame distilled prediction

Teacher imitation

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.
