Abstract
We propose an efficient regularized restoration model associating a spatial and a frequential regularizer in order to better model the intrinsic properties of the original image to be recovered and to obtain a better restoration result. An adaptive and rescaling scheme is also proposed to balance the influence of these two different regularization constraints, preventing an overwhelming importance for one of them from prevailing over the other, enabling them to be efficiently fused during the iterative deconvolution process. This hybrid regularization approach, mixing these two constraints and, more precisely, favoring a solution image that is both efficiently denoised [due to the denoising ability of a thresholding procedure in the discrete cosine transform (DCT) domain] and edge-preserved [due to the generalized Gaussian Markov random field (GGMRF) constraint]; yields significant improvements in terms of image quality and higher signal-to-noise ratio improvement results compared to a single GGMRF or DCT prior model and leads to competitive restoration results in benchmark tests, for various levels of blur, blurred signal to noise ratio (BSNR), and noise degradations.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
