METHODS AND APPARATUS FOR REFLECTIVE SYMMETRY BASED 3D MODEL COMPRESSION

摘要

Encoders and decoders, and methods of encoding and decoding, are provided for rendering 3D images. The 3D images are decomposed by analyzing components of the 3D images to match reflections of patterns in the 3D images, and to restore the components for further rendering of the 3D image. The encoders and decoders utilize principles of reflective symmetry to effectively match symmetrical points in an image so that the symmetrical points can be characterized by a rotation and translation matrix, thereby reducing the requirement of coding and decoding all of the points in 3D image and increasing computational efficiency.
