Abstract

fetched live from OpenAlex

Radiometric degradation is a common problem in the image acquisition part of many applications. There is much research carried out in an effort to deblur such images. However, it has been proven that it is not always necessary to go through a burdensome process of deblurring. To tackle this problem, different blur-invariant descriptors have been proposed so far, which are either in the spatial domain or based on the properties available in the Fourier domain. In this paper, wavelet-domain blur invariants are proposed for the first time for discrete 2-D signals. These descriptors, which are invariant to centrally symmetric blurs, inherit the advantages that this domain provides. It is also proven that the spatial-domain blur invariants are a special version of the proposed invariants. The performance of these invariants will be demonstrated through experiments.

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. 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.
