Abstract :
We are developing an intelligent presentation system. This type of system can handle live images of documents and drawings. In the system, documents are input using a computer-controlled camera; it can actively decide zoom parameters and glance directions of the camera in order to capture the whole document image in sufficient resolution. Scanned images are mosaiced into a large image. Then, links between document data and electronic data can be constructed by document analysis. In this research, we describe techniques in order to realize this type of system
