3D model retrieval is a very important research topic both in computer vision and computer graphics field. Most previous work is focusing on defining robust shape descriptor in order to get better retrieving accuracy. Unlike these work, we propose distance filter to improve the retrieving accuracy when using the existing shape descriptors. The main idea of distance filter is to eliminate distance...
With the development of face recognition and the wide use of RFID technology, the reliability and efficiency of identity verification is improved. The paper introduces an intelligence access control system, which consists of face detection based on skin model, RFID card processing and face recognition based on FNN. This system can be used in many fields, such as safety check in public activities,...
With the development of network education, the onLine question/answering (Q/A) system plays more and more important role. The traditional Q/A system need the teaChers to answer questions, which is low efficient. This paper introduces a model of an intelLigence Q/A system which is based on the expert system theory. And it analyzes how to construct the knowledge database, third it researChes on the...
