Abstract

fetched live from OpenAlex

A reciprocal-wedge transform (RWT) for space-variant sensing is presented. The RWT preserves linear features and facilitates translations in images. A concise RWT matrix representation and its applications to geometric transformations in the image plane are described. Like the log-polar transform, the RWT facilitates space-variant sensing, which enables effective use of variable-resolution data and the reduction of the total amount of sensory data. The RWT yields anisotropic variable resolution, which provides an alternative for active sensing when the shift of attention is primarily in one dimension. A projective model of the RWT is delineated and a hardware RWT projection camera is proposed. As an application of the RWT, the problem of road following in robot navigation and some initial experimental results are demonstrated.>

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.
