Abstract
Abstract Recently, Logvinenko introduced a new object‐color space defining a complete object‐color atlas that is invariant to illumination. 1 However, the existing implementation for calculating the new atlas's color descriptors is computationally expensive and does not work for all types of illuminants. A new algorithm is presented here that efficiently calculates the required color descriptors over large data sets and across a wide variety of illuminants. Its Matlab implementation has been made available online. The algorithm is then used to explore some features and possible applications of Logvinenko's color atlas. In particular, it is applied to images to investigate the perceptual correlates of the color descriptors; it is used to predict how images change under a change of scene illumination; and it is used to evaluate how changes in illumination and sensor sensitivities affect the mapping from the Munsell to NCS color atlases. © 2011 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
