Abstract: A method comprising: receiving an image of a scene, segmenting the image into a plurality of segments, obtaining at least one depth sample from each of at least some of the segments, and with respect to each of the at least some of the segments, assigning a value of the depth sample to each pixel in the segment, to create a depth image of the image.

Abstract: A method of and apparatus for making a three-dimensional object (2) made of a plurality of performed sheets (3), one atop the other, The method includes coating one side of one sheet (3) with adhesive using applicator (20), coating the adhesive with a release agent using applicator (22), bonding the opposite side of twice coating sheet (3) to a sheet (3) thereunder using adhesive on the surface of sheet (3) thereunder, and cutting twice coated sheet (3) using cutter (30). These steps are repeated until the desired number of sheets (3) is provided in a stack. The release agent is coated only in those areas of sheets (3) which will not be part of object (2), and cutting of each sheet (3) is along a contour corresponding to the contour of the same respective layer in object (2). After the steps have stopped, portion of the stack where the release layer is present and which is not part of object (2) is removed from the stack to give object (2).

Abstract: In a system for constructing a three-dimensional object by selective attachment of a plurality of sheets of flexible material, each sheet being cut along at least one contour line so as to subdivide the sheet into at least one object forming region corresponding to the shape of a layer of the object bounded by a corresponding contour of the object and at least one residue region not required in the constructed object, at least part of each object forming region being attached to object forming regions of adjacent layers, a method for facilitating the removal of the residue regions including producing selective attachment of at least part of a plurality of the residue regions to the residue regions of adjacent sheets in such a manner as to form, from at least part of the residue regions of a plurality of the sheets, a plurality of residue elements non-rigidly interconnected such that manual removal of each of the residue elements initiates removal of a subsequent one of the residue elements.
