Abstract
This communication presents an extensive survey of diverse image thresholding techniques applied to a standardized dataset of five 256x256 grayscale images.The evaluated methods include mean thresholding, histogram thresholding, edge thresholding, variable thresholding, and P-tile thresholding.Each technique's algorithm parameters are meticulously optimized to cater to the specific characteristics inherent in each image.This survey emphasizes the critical role of selecting appropriate thresholding techniques tailored to specific image characteristics and application requirements.Histogram thresholding emerges as a preferred method due to its consistent ability to achieve superior BPR results.Continued research efforts are crucial for advancing thresholding methodologies and expanding their applicability across diverse fields, such as study of medical images, remote sensing, and industrial quality control.

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
