3D triangular mesh matching through a sequence of registered 2D and 3D images
Bibliographic record
Abstract
VR systems were traditionally used for tasks relying on high-quality graphics rendering where virtual environments were entirely made of user-defined objects. We are foreseeing that serious breakthroughs will emerge, where 'augmented reality' environments will be created in a more dynamic fashion, using 2D and 3D data from computer vision sensors. Thus, virtual environments will not be made exclusively of user-defined objects, but also from real data. This data, after proper modeling to provide some behaviour and abstraction levels, will then be used to feed high-performance imaging systems. This paper deals with: 1) local surface modeling of the 3D data visible from each 2D viewpoint using a modified marching cubes algorithm; and 2) region matching of the local models (from neighboring views in the sequence) using color region clustering information from the 2D snapshots. Local models and the region matching information are used to build complete global models from a sequence of images.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
