A method of forming a refined depth map Dof an image I using a binary depth map Dof the image, said method comprising segmenting () the image into a superpixel image S, defining () a foreground and a background in the superpixel image S, to form a superpixel depth map D, intersecting () the respective foreground and the background of the superpixel depth map Dwith the binary depth map Ddetermined independently of the superpixel image S, to define a trimap T consisting of a foreground region, a background region and an unknown region, and forming the refined binary depth map Dof the image from the trimap T by reclassifying () the pixels in the unknown region as either foreground or background based on a comparison () of the pixel values in the unknown region with pixel values in at least one of the other trimap regions.
