Abstract
An omnistereoscopic image is a pair of panoramic images that enables stereoscopic depth perception all around an observer. An omnistereo projection on a cylindrical display does not require tracking of the observer's viewing direction. However, such a display introduces stereo distortions. In this article, we investigate two projection models for rendering 3D scenes in omnistereo. The first is designed to give zero disparity errors at the center of the visual field. The second is the well-known slit-camera model. For both models, disparity errors are shown to increase gradually in the periphery, as visual stereo acuity decreases. We use available data on human stereoscopic acuity limits to argue that depth distortions caused by these models are so small that they cannot be perceived.

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
