Abstract

fetched live from OpenAlex

This paper proposes a new approach for the multiscale segmentation and approximation of 2D contours. Its ultimate goal is to find the best set of constant curvature segments (straight line segments and/or circular arcs) to describe the contour in a way that respects its actual shape for recognition purposes. This approach is strictly based on discrete geometry principles, and the resulting algorithm named MuscaGrip (multiscale segmentation and contour approximation based on the geometry of regular inscribed polygons) computes, at multiple scales, two grouping processes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
