Abstract
In this article, a general framework for the retrieval of artistic line-drawings is introduced. It relies on the pictorial content, defined as a combination of the stylistic content and the visual features of the represented subject. First, we propose an automatic method for the extraction of stroke contours in line drawings, relying on a filtering of the level lines of images. Next, the radius of the drawing tool is estimated from these segmented strokes. This information then efficiently tunes the extraction of several geometric features, including the distribution of curvature, endpoints, junctions and corners of strokes. The efficiency of the proposed method is illustrated with several experiments on two classified databases of artistic line-drawings, and compared with an approach based on the curvature scale space (CSS). Retrieval experiments suggest that the proposed framework is able to handle the pictorial effect delivered by line drawings to a human observer.

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
