Three-dimensional (3D) shape modeling based on two-dimensional (2D) warping

An electronic device and method for 3D modeling based on 2D warping is disclosed. The electronic device acquires a color image of a face of a user, depth information corresponding to the color image, and a point cloud of the face. A 3D mean-shape model of a reference 3D face is acquired, and rigid aligned with the point cloud. A 2D projection of the aligned 3D mean-shape model is generated. The 2D projection includes a set of landmark points associated with the aligned 3D mean-shape model. The 2D projection is warped such that the set of landmark points in the 2D projection is aligned with a corresponding set of feature points in the color image. A 3D correspondence between the aligned 3D mean-shape model and the point cloud is determined for a non-rigid alignment of the aligned 3D mean-shape model, based on the warped 2D projection and the depth information.

11527015 · 2022-12-13 · ·

An improved method for coding video is provided that includes Virtual Reality (VR) sequences that enables more efficient encoding by organizing the VR sequence as a single 2D block structure. In the method, reference picture and subpicture lists are created and extended to account for coding of the VR sequence. To further improve coding efficiency, reference indexing can be provided for the temporal and spatial difference between a current VR picture block and the reference pictures and subpictures for the VR sequence. Further, because the reference subpictures for the VR sequence may not have the proper orientation once the VR sequence subpictures are organized into the VR sequence, reorientation of the reference subpictures is made so that the reference subpicture orientations match the current VR subpicture orientations.
