Information processing device and method

Abstract

The present disclosure relates to an information processing device and method which make it possible to suppress a reduction in coding efficiency. The method includes: decoding encoded data; generating motion vectors indicating positional differences between the vertices of a reference base mesh and the vertices of a current base mesh; reconstructing the current base mesh by applying the motion vectors to the vertices of the reference base mesh; and reconstructing a current mesh by applying a reference displacement vector to the vertices of the current base mesh. In addition, the motion vectors indicating the positional differences between the vertices of the reference base mesh and the vertices of the current base mesh are encoded; and control information relating to the application of the reference displacement vector to the vertices of the current base mesh in the reconfiguration of the current mesh is encoded. The present disclosure is applicable, for example, to information processing devices, electronic instruments, information processing methods and programs.
