Abstract

fetched live from OpenAlex

Color noise in the form of clusters of color non-uniformity is a major negative quality factor in color images. This type of noise is significantly more pronounced in CMOS cameras with increasingly smaller pixel sizes (e.g., 1.75μm and 1.4μm pixel sizes). This paper identifies and quantifies temporal noise as the main factor for this type of noise. As well, it is shown how differences in R/G/B responses and as well possible presence of R/G/B-response non-linearity can exacerbate color-blotch noise. Furthermore, it is shown how run-time averaging can effectively remove this noise (to a large extent) from a color image-if capture condition permits.

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.

Full frame distilled prediction

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.
