Auto-detection of male genital flashers

Men who drop their trousers and display their genitals on the internet can now be detected more reliably and automatically, is the thrust of this new study:

(Thanks to investigator Kumiko Odeki for bringing this to our attention.) The authors, at University of Colorado at Boulder, McGill University, and Ohio State University, explain:

“Online video chat services such as Chatroulette, Omegle, and vChatter that randomly match pairs of users in video chat sessions are fast becoming very popular, with over a million users per month in the case of Chatroulette. A key problem encountered in such systems is the presence of flashers and obscene content…. This paper presents SafeVchat, a novel solution to the problem of flasher detection that employs an array of image detection algorithms…. The paper introduces a novel, motion-based skin detection method that achieves significantly higher recall and better precision.”
