Abstract

fetched live from OpenAlex

A method for simultaneously and instantly obtaining both a three-dimensional (3D) surface and its inclination angle distribution from a single image captured by an imaging system equipped with a coaxial multicolor filter that integrates deep neural networks (DNNs) is proposed. The imaging system can obtain a light-ray direction in the field of view through one-shot color mapping. Light rays reflected from a 3D surface, even if it has microscale height variations with a small inclination angle distribution, can be assigned different colors depending on their directions by the imaging system. This enables the acquisition of the surface inclination angle distribution. Assuming a smooth and continuous 3D surface, it is possible to reconstruct the surface from a single captured image using DNNs. The DNNs can provide the height variations of the 3D surface by solving a nonlinear partial differential equation that represents the relationship between height variation and the direction of light rays. This method is validated analytically and experimentally using microscale convex surfaces.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
