Prompt

Transform this image into an Alpha Matte visualization with opaque foreground areas in white, fully transparent background areas in black, and intermediate opacity in gray. Preserve delicate hair, fine fibers, and translucent edge details through soft, precise transitions rather than uniformly blurred outlines. Keep the original subject and composition.

Identify

Edges are represented with soft, translucent transitions.

Principle

A soft alpha mask1 contains values between fully visible and invisible.

Try it out

Display the subject against a different background.

Classification

Schematic visualization, not neural inference2.

02 Menger - Prism Shape x Quaternion 1565501587 8K alphaA grayscale image representing a complex 3D shape. It serves as a schematic alpha matte where white indicates full opacity and black indicates transparency, defining the visibility of the object for digital compositing.PantheraLeo1359531 · CC BY-SA 4.0 · Wikimedia Commons
