Abstract

fetched live from OpenAlex

The application of 2-D Kalman filtering to the restoration of images degraded by linear space invariant blur and additive white Gaussian noise is described. R.P. Roesser's 2-D local state space model (1975) is used to represent the image process and the blur process. As a result, a simple procedure for establishing the Kalman filter equations is obtained. This scalar filtering algorithm provides a computationally feasible procedure for the restoration of large images. To speed up the Kalman filtering procedure, a VLSI systolic array structure is presented. For higher speed and higher utilization of this processor, a diagonal scanning method is suggested. The filter scheme can be easily extended to the causal image model and the causal blur model with nonsymmetric half-plane support.>

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.
