摘要： A progressive coding and decoding method of three-dimensional (3D) mesh data used in the fields of motion picture experts group-4 synthetic and natural hybrid coding (MPEG-4 SNHC), virtual reality modelling language (VRML) and the like. In transmitting 3D objects composed of 3D mesh data, it is very important to progressively restore transmitted data as well as to effectively code the 3D mesh data. In the progressive restoration, in the event that a transmission data error is generated, partial restoration of the transmitted data is allowed. Thus, it is possible to minimize the amount of mesh data to be transmitted again. The progressive restoration method which is resistant to such transmission errors can be effectively applied in wireless communications or low transmission rate communications. In the progressive coding and decoding method, connectivity, geometry and photometry necessary for progressively coding 3D mesh data are constructed and then coded/decoded, thereby providing data resilience against errors.

摘要： In a prediction method usable with synthetic and natural hybrid coding (SNHC) field or a virtual reality markup language (VRML) the difference between immediately prior information (most adjacent information) and input property information is obtained, considering the immediately prior information as the prediction value. The difference is used as a prediction error signal. A predictor having an order of 1 is used. When the output value of the predictor is fixed to 0, the prediction error signal becomes identical to an original signal. Therefore, the operation is the same as in the case where there is no predictor. The correlation of the input property information is used in order to control two operation modes of the predictor. Namely, auto-correlation is obtained from the input property information.
