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

摘要

This paper defines a spatiotemporal mutual information on the pixels of a given video image on the basis of information theory (Shannon's communication theory), which can be interpreted as the theoretical estimation of interested features for human being. As an application of this spatiotemporal mutual information, we propose a method of producing a vivid video image of the distance learning by using the computer controlled camera operation and switching of plural camera images on the basis of the video image processing. Results of the questionnaire survey for the video image produced by the method confirm the effectiveness of our approach.
