Abstract
Though the wavelet threshold algorithm has been demonstrated to be a very effective tool to denoise the images with low levels of noise, it usually losses the power to well preserve meaningful details in images. To this end, this paper proposed an adaptive threshold denoising method for images that are usually interfered by noise on the Wireless Multimedia Sensor Network (WMSN). First, a scale parameter equation was defined according to different sub-band characteristics after the images were subject to wavelet decomposition, so as to determine the adaptive optimal threshold suitable for each scale level; Second, a new derivable threshold function was designed in this paper; Third, after comparison, proper wavelet basis function was selected for image denoising accordingly. Moreover, the test results on several test images proved the superiority of the proposed method over some classical methods in terms of PSNR and MSE.

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
