ENCODING/DECODING APPARATUS AND METHOD FOR ORIENTATION INTERPOLATOR NODE DATA

摘要

An encoding/decoding apparatus and method for an orientation interpolator node are provided. The encoding/decoding apparatus for an orientation interpolator node, which provides rotational information of an object in a 3-dimensional space, is formed of "key information" which indicates a time when a rotational movement occurs and "key value information" which indicate s a rotational posture corresponding to the time. A predictive coding apparatu s is used in the encoding process for compressing the information of the key a nd key value information. Therefore, in encoding an input orientation interpolator node in an information compression method of a predictive encoding method, the efficiency of encoding is improved and an reverse rotation due to an encoding error from lossy coding can be corrected.
