Abstract

fetched live from OpenAlex

As most cameras are currently built to be used alongside machine learning algorithms, image quality requirements still emanate from human perception. To redefine key performance indicators (KPI) for machine vision, optical designs are tested and optimized before their conception using differentiable simulation methods and gradient backpropagation to jointly train an optical design and a neural network. Although this helps to design optical systems for improved machine learning performance, it remains unstable and computationally expensive to model complex compound optics such as wide-angle cameras. We focus on optimizing the distortion profile of ultra wide-angle designs as it constitutes the main KPI during the optical design. Along the way, we highlight the benefits of controlling the distortion profile of such systems, as well as the challenges related to using learning-based methods for optical design.

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.
