WebThe Matting Equation. A image is a composite of foreground and background. Hence each pixel intensity is a linear combination of a foreground and background that can be written as : Ii = αi*Fi + (1-αi)*Bi (1) In matting equation all quantities on the right of the equation are unknown. Thus for a color image we have 7 unknowns and 3 equations. WebMatting and compositing are important operations in the production of special effects. During matting, foreground elements are extracted from a film or video sequence. During compositing, the extracted foreground elements are placed over novel background images. Traditional approaches to matting include blue-screen mattingand rotoscoping.

WebIn this paper, we propose a Virtual Multi-modality Foreground Matting (VMFM) method to learn human-object interactive foreground (human and objects interacted with him or her) from a raw RGB image. The VMFM method requires no additional inputs, e.g. trimap or known background. WebThis process, dubbed "matting" or "pulling a matte," is most commonly used to separate the foreground and background elements of an image, and these images are often individual frames of a video file. In case of video, matting methods can use temporal relations as additional information.
