Abstract

With the popularity of social media services, academic lecture slides could be shared immediately and discussed among hundreds of friends, which may extend the audience scope. Aiming at slide recording in speaker-occlusion scenes, we present our prototype system SRec, an automatic real-time slide capturing and sharing system. Based on depth information, it filters speaker body occlusion, recovers slide content, generates image/voice digital notes and shares them through social media services. The experiment shows SRec could capture and recover common text and picture slides shown in LCD and projector screens efficiently.
