Prompt

Transform this image into an M-LSD Structural Lines visualization, emphasizing long, straight segments along existing architectural edges, furniture, and other linear forms. Draw thin white segments on a darkened photographic base, omit curved contours and fine textures, and retain clean endpoints and intersections. Keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Long straight lines reduce the image to its structural form.

Principle

The Hough line map1 is used as a technical approximation.

Try it out

Test the same method on buildings.

Classification

Schematic visualization, not neural inference2.
