Abstract
We propose a signal processing method for the CMOS Buried Quad Junction (BQJ) photodetector employed for multi-label fluorescence detection. It serves to quantify label components in an arbitrary mixture with improved signal-to-noise ratio. The proposed method includes least squares optimization and statistical data preprocessing based on Principal Component Analysis (PCA). The method was applied to the BQJ as well as to Buried Double Junction (BDJ) and Buried Triple Junction (BTJ) detectors. The obtained results show that BQJ case achieves best accuracy in label quantification compared to BDJ and BTJ detectors in any tested configurations. The statistical data preprocessing approach was also evaluated: 5dB SNR improvements for an example case of two-label mixture (Green-Red excitation with optical power over 28pW).

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
