Abstract
We present a primal-dual coding video camera, an optical device that captures video in which the flow of light through a scene has been manipulated. This camera has the ability to visualize indirect transport effects (caustics, inter-reflections, volumetric scattering, etc.), measure direct-only light paths (surface reflections), capture transport that occurs within specific regions of 3D space, and perform structured light imaging in the presence of complex indirect effects. The operating principle behind this technology is to simultaneously code the light that goes into a scene with the light that comes out. Specifically, over the course of a single camera exposure period, we project a sequence of light patterns onto the scene in lockstep with a second sequence of mask patterns that modulates the light incident on the camera sensor. This optical procedure creates RAW, unprocessed photos where a scene's light transport function appears to have changed.

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 it
