Original Abstract Submitted
A 3D data decoding apparatus for decoding encoded data includes a mesh prediction unit configured to derive a prediction position of a base mesh vertex position from the encoded data, and an arithmetic decoder configured to arithmetically decode a prediction residual. The arithmetic decoder decodes a part of a beginning of a prefix of an absolute value of a coefficient of the prediction residual by using a context and adds the prediction position and the prediction residual to derive the base mesh vertex position.
