Abstract
Depth from defocus based methods rely on measuring the depth dependent blur at each pixel of the image. A core component in the defocus blur estimation process is the depth variant blur kernel. This blur kernel is often approximated as a Gaussian or pillbox kernel which only works well for small amount of blur. In general the blur kernel depends on the shape of the aperture and can vary a lot with depth. For more accurate blur estimation it is necessary to precisely model the blur kernel. In this paper we present a simple and accurate approach for performing blur kernel calibration for depth from defocus. We also show how to estimate the relative blur kernel from a pair of defocused blur kernels. Our proposed approach can estimate blurs ranging from small (single pixel) to sufficiently large (e.g. 77 x 77 in our experiments). We also experimentally demonstrate that our relative blur estimation method can recover blur kernels for complex asymmetric coded apertures which has not been shown before.

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
