Title:
【発明の名称】エラー回復性を有する漸進的三次元メッシュ情報の符号化/復号化方法
Document Type and Number:
Japanese Patent JP3361492
Kind Code:
B2
Abstract:
A progressive and error resilient 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 and error-resiliently 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 retransmitted and the standby time of a user. 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 and error-resilient coding and decoding method, connectivity, geometry and photometry necessary for progressively coding 3D mesh data are constructed and then coded/decoded, thereby allowing incremental build-up and error resilience.
