Real-Time Whiteboard Capture System
Real-Time Whiteboard Capture System captures whiteboard lecture video in real time and extracts newly written pen strokes. Unlike other systems, it does not require special instruments such as electronic pen or whiteboard. The captured video images are classified into pen strokes on the whiteboard, foreground (person in front of the whiteboard) and Whiteboard Background Model (whiteboard withou...
متن کاملWhy take notes? Use the whiteboard capture system
This paper describes our recently developed system which captures both whiteboard content and audio signals of a meeting using a digital still camera and a microphone. Our system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the captured image sequence. It also automatically produces a set of key frames representing all the...
متن کاملSelf-calibrating a real-time monocular 3d facial capture system
This paper addresses the problem of obtaining 3d detailed reconstructions of human faces in real-time and with inexpensive hardware. We present an algorithm based on a monocular multi-spectral photometric-stereo setup. This system is known to capture high-detailed deforming 3d surfaces at high frame rates and without having to use any expensive hardware or synchronized light stage. However, the...
متن کاملSpoken dialog system for real-time data capture
This papers reports on the development of spoken dialog system as a tool for real-time data collection for healthcare, life and behavioral science. Specifically, we implemented a dialog system, Pain Monitoring Voice Diary, for monitoring chronic pain patients. We discuss the requirements and characteristics of this application, specifically, the needs for adaptive level of user support and high...
متن کاملReal-time 3D Motion Capture
We describe a real-time 3D computer vision system for detecting and tracking human movement and providing a person with control over the movement of a virtual puppet. Multiple cameras observe a person; silhouette analysis and template matching achieve real-time 3D estimation of human posture. A dynamics/kinematics model of human body and Kalman filter are utilized to help the tracking process a...
