ABSTRACT:
Method of wavelets-based multiresolution representation of a 3D image object. A center of an original 3D mesh image is set as an original of a new coordinate system, and respective coordinates of the original 3D mesh image is converted to the new coordinate system. After the coordinate conversion, the 3D mesh image is divided into a plurality of local meshes, of which boundary and inner coordinates are mapped. Next, a division level for the basis meshes is determined, and the basis meshes are divided accordingly. A parameter for local meshes divided from the basis meshes is determined. By a composition of boundaries of the reconstructed local meshes, the original 3D image object can be converted into an object to which wavelets can be applied, and as a result, the converted object can be represented at various resolutions with coefficients.
