Online detection of potato drying stages based on improved YOLOv7-tiny model
Bibliographic record
Abstract
To realize accurate online identification of different stages of the agricultural product drying process and overcome the limitations of empirical models, this study proposes a method for online identification of agricultural product drying stages based on machine vision, which enhances the YOLOv7-tiny model by adding an attention mechanism module to the feature layer and the up-adoption process. The recognition results were compared and evaluated with those of other versions of YOLO, Faster R-CNN, SSD, EfficientDet, and an unimproved YOLOv7-tiny network. The results showed that the average recognition accuracy of this method for the constant drying stage, first drying stage deceleration and second drying stage deceleration of potato slices reached 98.8%, which was superior to that of the model without the attentional mechanism module. This lays the foundation for the establishment of an on-line adaptive drying model for agricultural products.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
