Abstract
In this paper, a new 2D-Shape-encoding scheme is introduced which is based on the idea of the Angle-Of-Sight (AOS). Using this scheme, a shape can be efficiently transformed into a 1D signature by recording the AOS-vs-distance of each boundary point with'respect to a shape-specific Chord-Of-Sight (COS). The COS is selected by using an extension of the notion of shape boundary, to the idea of shape-specific points and the characteristic ellipse (CE). The AOS signature has many important properties including: It is information-preserving, and thus unique; It does not require boundary smoothing; It has its own select- able smoothing property; It can provide a set of multi-scale representations by means of a simple operation; It is transformation-invariant; It is defined at all points; It preserves symmetries. As well, for matching purposes, a two-level matching process is proposed using a global meas- ure (the eccentricity of the CE of a shape) and a dissimilarity measure based on the AOS signature. The encoding and matching techniques developed have been tested %with 35 manufactured objects. The results obtained show that the AOS signature and the two-level-matching technique are quite effective and reliable for the recognition of 2D-shapes of typical manufactured objects.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
