Abstract
An object is composited digitally from an input image onto a destination image. A background model is created and a frame of an input image containing the object is obtained. An alpha image is created in which each pixel is either a zero, indicating it is not part of the object, or a one, indicating that it is part of the object. The effect of shadows emanating from the object is reduced. A set of templates is then derived to allow holes or gaps in the object created during the compositing process to be filled to a large extent. The object is blended onto a destination image using the alpha image as a blending coefficient.
