image matting

What is Image Matting Natural image matting is a fundamental computer vision task, which aims to predict an alpha matte of the foreground object from a given image. An image can be represented by a linear combination of foreground and background, with a blending of a parameter alpha. Mathematically, image matting is formulated as: Ii = αiFi + (1 − αi)Bi , where Ii, αi, Fi and Bi are observed colour value, alpha value, foreground value and background value of pixel i, respectively....
