Abstract
The bandwidth required to transmit stereoscopic video signals is nominally twice that required for standard, monoscopic images. An effective method of reducing the required bandwidth is to code the two video streams asymmetrically. We assessed the impact of this bandwidth- reduction technique on image quality and overall sensation of depth. Images from the right-eye stream were spatially filtered on image quality and overall sensation of depth. Images from the right-eye stream were stream were spatially filtered to half and quarter resolution. Subsequently, the images were processed using an MPEG-2 codec at bit-rates of 6, 2, and 1 Mbit/s. Subjects assessed image quality and depth using a double-stimulus, continuous-quality scale method. It was found that perceived depth was relatively robust to spatial filtering and bit-rate reduction. Image quality was affected more by bit-rate reduction than by spatial filtering and, at the lower bit rates, ratings were much higher for stereoscopic than for non-stereoscopic sequences. The results indicate that asymmetrical coding of stereoscopic sequences can be an effective means of reducing bandwidth for storage and transmission.

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
