An installation of privacy-safe see-through vision

A number of surveillance cameras are in operation for security in outdoor scene in our modern community. However, it is often criticized for privacy problem. Our previously proposed see-through vision is a system that provides benefit for ordinary people who might be subjects of surveillance cameras. It enables people to see-through obstacles and watch places behind them. Since the see-through vision is a powerful tool that may violate privacy of other people, we then need a good solution that can make a good balance between the benefit and the privacy. In this paper, we propose privacy-safe see-through vision. Technically, we utilize a marker-based camera tracking for achieving the see-through vision which makes our system more reliable and easy set-up. We have demonstrated the system in a shopping mall in Kyoto. Comments from ordinary visitors indicate the system serves as what it is intended to be.
