Predicting Crest Geometry from Marked Sketches

Predict the footprint and distance from the moon mark of each crest used to place a marked garment region into shadow, rather than determining these geometric parameters with a fixed rule.

Background

The proposed sketch-to-scene system uses star marks to infer the directional light and moon marks to indicate garment regions that should fall into shadow. To enforce the moon-marked shadows, the method adds one crest beside each moon mark; the crest’s side is selected according to the predicted light, while its height is derived from the predicted displacement field.

The crest footprint and its distance from the moon mark are not inferred from the sketch or learned from data. Instead, both are fixed by a rule. The authors explicitly identify learning or predicting these two parameters as an unresolved next step, making this a concrete open problem concerning more adaptive geometric displacement.
