Abstract

fetched live from OpenAlex

We present a novel image denoising method utilizing coded aperture photography. Our approach captures an image that is slightly optically defocused by a coded aperture. This allows us to more effectively reduce noise while high frequency of image structures are protected by the coded aperture image. We analyze the effectiveness of coded aperture in decoupling noise frequency from high frequency of image structures. A novel frequency-aware regularization is proposed to denoise and to restore sharp image from a noisy slightly out-of-focus coded aperture image. The effectiveness of our approach is demonstrated on various challenging examples with quantitative and qualitative comparisons to results of state-of-the-art denoising methods.

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.
