Feature Extraction for Digital Object in Pervasive Computing Environment

In view of the multiplicity of the information in pervasive computing environment, this paper propose a new kind of mathematical model-V-system with multi-resolution property, with which we can do spectrum analysis for the whole multimedia data. By doing global analysis to two and three dimensional digital geometric objects, the global characteristics of the corresponding digital information is obtained, and the digital information is then accurately reconstructed. Further, recognition and classification on the geometric information can be done.
