Matting techniques

Matting techniques are methods used to separate a subject from its background in an image or video, creating a clean cutout. They analyze the image's pixels to distinguish foreground elements (like a person) from the background (such as a green screen or complex scene). Techniques include chroma keying, which uses a uniform background color, and more advanced algorithms that handle intricate edges and semi-transparent areas, like hair. These methods enable seamless compositing, allowing the subject to be placed into different environments convincingly. Overall, matting enhances visual effects by accurately isolating subjects from their original backgrounds.
