Abstract

fetched live from OpenAlex

This paper defines a new measure of texture granularity based on image particles obtained via the mean shift segmentation algorithm. A given texture is segmented a number of times to produce a scale-space hierarchy of increasingly finer images. In each instance, the segmented texture of the previous layer is used as a mask in the segmentation of the current layer. In this way, finer regions are forced to become nested within the larger enclosing regions of the previous layer. Next, the numerical differences between each layer and its predecessor are computed. Empirical evidence indicates that the most accurate estimate of the actual texture particle size occurs between the two layers of greatest numerical difference. Using this difference information, the overall granularity of the texture is calculated. Unlike existing measures of granularity which focus mainly on gray-level variations, this measure describes a texture's granularity in terms of its intrinsic micro structure. It is expected that this interpretation of granularity will more closely approximate that of the human visual system.

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.
