LetterTwitter: Smart Mailbox for Spam-filtered Notification of Received Letters

摘要

We propose a smart mailbox called "LetterTwitter" that can automatically capture dropped snail mail (s-mail), classify pictures into several categories (e.g., letters or flyers), and upload categorized pictures to the Web. Users can easily get spam-filtered notification of received letters using PCs or cellular phones equipped with common web browsers.
