Abstract:
A computer-implemented method for decomposing a plurality of images of a three-dimensional scene into a plurality of layers, comprising using a computing device to:provide a sequence of images of a three-dimensional scene, with each image being acquired from a unique viewpoint of the scene; rectify each image of the scene to a first image of the scene to remove affects of camera rotation; estimate high entropy image features in the first image; estimate parameters of a number of scene models from the high entropy image features, wherein a first scene model has one layer, and each subsequent scene model has one more layer than a previous scene model; determine the most probable model of the number of scene models; during the determination of the most probable model, for the first image, implicitly assign pixels representing the high entropy image features to corresponding layers in the most probable model, and, for each other image of the scene, implicitly assign corresponding pixels from the rectified images to the corresponding layers in the most probable model; and probabilistically assign pixels not representing high entropy features to the most likely layer of the most probable model for each such pixel.
