Abstract
Virtual Vision advocates developing visually and behaviorally realistic 3D synthetic environments to serve the needs of computer vision research. Virtual vision, especially, is well-suited for studying large-scale camera networks. A virtual vision simulator capable of generating "realistic" synthetic imagery from real-life scenes, involving pedestrians and other objects, is the sine qua non of carrying out virtual vision research. Here we develop a distributed, customizable virtual vision simulator capable of simulating pedestrian traffic in a variety of 3D environments. Virtual cameras deployed in this synthetic environment generate imagery using state-of-the-art computer graphics techniques, boasting realistic lighting effects, shadows, etc. The synthetic imagery is fed into a visual analysis pipeline that currently supports pedestrian detection and tracking. The results of this analysis can then be used for subsequent processing, such as camera control, coordination, and handoff. It is important to bear in mind that our visual analysis pipeline is designed to handle real world imagery without any modifications. Consequently, it closely mimics the performance of visual analysis routines that one might deploy on physical cameras. Our virtual vision simulator is realized as a collection of modules that communicate with each other over the network. Consequently, we can deploy our simulator over a network of computers, allowing us to simulate much larger camera networks and much more complex scenes then is otherwise possible.

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
