Production of video images by computer controlled camera operationbased on distribution of spatiotemporal mutual information

摘要

This paper defines a spatiotemporal mutual information on thepixels of a given video image on the basis of information theory(Shannon's communication theory), which can be interpreted as thetheoretical estimation of interested features for human being. As anapplication of this spatiotemporal mutual information, we propose amethod of producing a vivid video image of the distance learning byusing the computer controlled camera operation and switching of pluralcamera images on the basis of the video image processing. Results of thequestionnaire survey for the video image produced by the method confirmthe effectiveness of our approach
