Abstract

fetched live from OpenAlex

This paper addresses the problem of camera pose recovery from spherical images. The 3D information is extracted from a set of panoramas sparsely distributed over a scene of interest. We present an algorithm to recover the position of omni-directional cameras in a scene using pair-wise essential matrices. First, all rotations with respect to the world frame are found using an incremental bundle adjustment procedure, thus achieving what we called cube alignment. The structure of the scene is then computed using a full bundle adjustment. During this step, the previously computed panorama orientations, used to feed the global optimization process, are further refined. Results are shown for indoor and outdoor panorama sets.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
