Abstract

fetched live from OpenAlex

Many methods are available for image mosaicing most of which are not useful because they either (1) require a great deal of overlap between images, or (2) if they work for restricted sub-problem (translation, rotation or zooming) they would not work for the others. While numerous methods exist for accurately calculating translational shifts, no method was found that could handle rotations of angles greater than 15 degrees, or for scaling. In this paper, a new method using Zernike moments is presented to solve for the translational registration, rotational registration (2D and 3D) and zooming all at the same time. This method was tested on different sets of images with translational shifts, rotational shifts and zooming. The method is very fast, efficient and does not require any human interaction, and the results proved to be very accurate.

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.
