Design of a Stochastic Computing Architecture for the Phansalkar Algorithm
Bibliographic record
Abstract
Binarization plays a key role in image processing. Its performance directly affects the success of subsequent character segmentation and recognition. The Phansalkar algorithm performs excellent in processing heavily degraded or poor-quality images. However, this algorithm incurs significant hardware costs. In this article, efficient stochastic computing (SC) functions and an architecture are proposed for the Phansalkar algorithm. Highly accurate stochastic elements are designed for this architecture, including a stochastic mean circuit (SMC), a stochastic unipolar subtractor (USUB), a stochastic square root circuit (SQRT), and a stochastic exponential circuit (SEXP). Simulation results show that the SC architecture using 64-bit streams for the Phansalkar algorithm provides sufficient accuracy. Physical implementation indicates the effectiveness of the proposed architecture in lowering hardware costs for this algorithm compared with the binary counterpart.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
