Abstract

fetched live from OpenAlex

This paper presents a region growing technique for texture segmentation. The technique is implemented by comparing local region properties, which are represented by a 2-D autoregressive (AR) model in a hierarchical manner. It is able to grow all regions in a textured image simultaneously starting from initially decided internal regions until smooth boundaries are formed between all adjacent regions. A multilayer neural network is used in the local region identification procedure to establish a 2-D AR model for a textured region and to compute the region properties for the segmentation. The performance of the segmentation technique is shown by experiments on natural textured images.>

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.
