How to use Image Preprocessors
Getting started
Extract a line map from an image with the HED detector. Use the result to inspect contours before a compatible conditioning workflow.
Review your result
Check that important outlines survive and background texture does not overwhelm the subject.
Inputs and settings
Provide image_url. safe selects the detector’s safe variant; scribble selects its scribble variant.
Change one variant at a time and compare the maps. These controls process the source; they do not describe a new scene.
