VRAPS (Visual Rhythm-based Audio Playback System) is an interactive multimedia application that uses a novel visual rhythm detection technique to allow a user to control the playback speed of an audio signal by moving in front of a video camera. As traditionally defined in the context of music, a beat represents a distinctive musical event such as the hitting of a drum or the start of a new melodic...
A 671G0PS/W Semantic Analysis SoC (SASoC) is implemented in 90 nm CMOS technology. Two stream processing systems are integrated with a power-aware frequency scaling technique to simultaneously accelerate video processing and machine-learning algorithms. The input data rate reaches 76.8 Gpixel/s for video processing and 51.2 Gdimension/s for machine-learning algorithms.
Exploration techniques of video knowledge have been proposed for years to help people discover the details about videos. However, existing systems still yield limited information for users. In this paper, we present a video knowledge browsing system, which can establish the framework of a video based on its summarized contents and expand them by using online correlated media. Thus, users can not only...
