1. A method for replacing image information in an image, the method comprising: obtaining an image of a scene; obtaining a depth map of the scene; defining a depth surface in the depth map, wherein the depth surface includes at least two different depth values; defining at least one portion of the image based on the depth surface; and replacing the at least one portion of the image with image information; wherein the step of defining the depth surface comprises: identifying a portion of the obtained image that corresponds to a selected object in the scene; mapping the portion of the obtained image that corresponds to the selected object in the scene to a set of coordinates in the depth map; determining a surface of the selected object based on the mapping of the portion of the obtained image; fitting a surface model to the determined surface of the selected object; and forming the depth surface by extending the surface model along an entire width direction and an entire height direction of the scene as mapped in the depth map.
