Abstract

fetched live from OpenAlex

In structure from motion or similarly in monocular SLAM problems, spatio-temporal image variations, motion and scene geometry are intimately related and in the absence of such a constraint, unsupervised deep learning methods often tend to state the problem under multiple constraints. We readdress the problem of 3D interpretation estimation as an unsupervised deep learning process where depth and camera motion are learned to satisfy the 3D brightness constraint for rigid objects. We introduce for the first time a new learning paradigm where the spatio-temporal variations of image sequences are coupled to 3D interpretation to minimize the loss without need to add more ad-hoc constraints that are not related to the 3D interpretation. Experimental results show that our method competes and sometimes outperforms the state-of-the-art methods.

Full frame distilled prediction

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.
