Abstract

fetched live from OpenAlex

A model-based pose determination algorithm for segmented 3-D images has been developed using the geometric hashing method and the interpretation tree. Its major advantage is an intensive off-line model preprocessing stage, where model information is indexed into a hash-table using minimal, transformation invariant features. This enables the on-line recognition algorithm, with its voting procedure, to be particularly efficient. Once the correspondence of a minimal set of features is established by the geometric hashing method, the interpretation tree is used to obtain the complete set of correspondences between the object's model and the segmented range image. The best pose estimate is then found using a constrained least-squares method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
