The aim is to present SketchCrafter as a training-free framework for effective sketch extraction.
Introduced edge-based initialization for generating sketches from content images.
Implemented a dual-control mechanism for local and global coherence in sketch features.
Utilized a content encoder and a global style encoder for improved style fidelity.
SketchCrafter shows superior content alignment compared to existing methods.
Achieved high fidelity in style representation, proving effective at maintaining source image integrity.
Performed well across various benchmarks, confirming its efficacy in training-free sketch extraction.

No takes yet. Share an insight, caveat, or question.

Randomized trial demonstrates effective sketch extraction, highlighting content alignment and style fidelity.
