The MPEG-7 Standard and the Content-Based Management of Three-Dimensional Data: A Case Study
نویسندگان
چکیده
Content-based management of three-dimensional data in the framework of the MPEG-7 standard is considered. An overview on MPEG-7 and three-dimensional data is presented. Descriptors and description schemes suitable for three-dimensional data are introduced and their integration in the framework of MPEG-7 is detailed. The shape descriptors are based on cords, wavelet transform and three-dimensional statistical moments. Implications of the normative and the non-normative parts of the standard are analyzed and their relations are considered. The descriptors and description schemes are evaluated according to MPEG-7 criteria. Experimental results indicating the potential of the descriptors are presented. Some considerations on dynamic scenes are introduced.
