Abstract

fetched live from OpenAlex

Manufacturing flexibility can benefit from the use of non-contact computer-vision based shape-recovery methods. In this paper, a novel hybrid scheme is proposed, which combines stereo-vision and shape-from-shading recovery for obtaining more reliable absolute shape information about a viewed object. This iterative scheme first utilizes stereo-vision to obtain basic depth information along the boundary and through the surface of the object. Subsequently, the depth map is input to the shape-from-shading algorithm to obtain feature patterns. This information is fed back to the stereo-vision algorithm to improve upon the accuracy of the depth map. A cost function, in the form of a weighted sum of distances from smoothness and brightness, is utilized for the pattern matching. The performance of the proposed scheme was verified via experiments.

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.
