Abstract

fetched live from OpenAlex

In this paper, a new color filter array (CFA) interpolation method for digital still cameras is introduced. Building on the computed edge-sensing map and a refined color difference model, a new correlation-correction algorithm is introduced. Due to edge-sensing interpolation mechanism and correction steps performed for each color channel, the proposed interpolation scheme is able to overcome the limitations of existing CFA based image acquisition solutions and restore color images without introducing false colors, edge blurring or visual artifacts. Moreover, the proposed method is described in a novel vector notation, which readily unifies previously developed schemes. Simulation studies indicate that the proposed method is computationally efficient and yields excellent performance, in terms of subjective and objective image quality measures, while outperforming well-known and widely used CFA interpolation methods.

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.
