Abstract

fetched live from OpenAlex

Traditional character animation has superiority in conveying stylized information about characters and events, but producing it requires a lot of labor and time. Computer generated animation improves greatly on efficiency, but is poor in expressing stylized motion. In this paper, we propose a sketching-based animation synthesis system. The system contains an interface for the user to draw the sketches or load sketch images. Then the system extracts 2D pose from the input strokes and maps the 2D pose to 3D pose that is in a motion capture database. During the mapping, a series of matching 3D pose candidates are found. The user can select the most satisfying candidate as the 3D key pose for the later animation synthesis. The system synthesizes an animation based on the 3D key poses by finding a path in the motion capture database and generating transition motions if needed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
