Abstract

fetched live from OpenAlex

Conventional image capture and display devices are prone to various form of optical artifacts. These artifacts are inherent to the non-ideal behavior of the various optical elements such as sensors, displays, lens, prisms, mirrors, light sources. These optical distortions may be corrected digitally by image warping technology. Image warping may be defined as a process of dynamically resampling a regularly spaced input image to produce a nonregular spacing output image. In this paper, one-pass algorithm for digital image warping is presented. It is based on anisotropic circularly symmetric antialiasing filtering over elliptical or rectangular footprint. It is shown that developed design provides flexibility and better image quality than known two-pass methods. The proposed algorithm has been embedded into a few display processors for optical distortion corrections both at image acquisition and displaying sides.

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.
