Technology Showing research presentations from Hewlett-Packard Labs with a new type of a camera-projector system that allows E-Z authoring of video presentations I-Jong Lin and Other Researchers at HP Labs, Palo Alto, CA http://www.hpl.hp.com/research/isl/activeshadows/ A Few Presentations of Research Going on at HP-Labs in Video Podcast Format Using a special projector-camera system with Active Shadows software, that was developed at HP-Labs by I-Jong Lin, we can easily author presentations about our research and going-ons at Hewlett Packard. The system captures the presenters' directed interaction with a projected/displayed digital images in real-time, allowing the simple creation of multi-layered video output. The Active Shadows system technology creates highly quality overlaid video without the hassle of interacting with a bluescreen or needing a dedicated bluescreen room; it allows the presenters to create high-quality video presentations while allowing the presenter to focus on what they do best -- giving a presentation. en-us ℗ & © 2005 I-Jong Lin I-Jong Lin i-jong.lin@hp.com My first attempt at putting semi-educational presentation content on Video iPod I-Jong Lin My First Foray into the Video Podcasting A video snippet from the Active Shadows system to see whether my E-Z presentation publishing process actually works.

It introduces the concept of camera-display feedback loop, i.e. where a camera of a computer is pointed at its own display, and the concept that the space between the camera and display can be used to capture physical interactions with images on the display. I-Jong Lin The point of this line of research. This is the first video podcast episode to explain my work called Active Shadows, a special camera projector system used to capture physical interaction with a digital image. We lay out the groundrules for this type of technical presention on iTunes and a video ipod, and how it differs from a "real" technical talk. We go through simple computer setups for 1) the usual day-to-day cubicle dweller interaction, 2) the video conferencing case, and then 3) the special case where the computer's camera is pointing at its own display. The third case is a special camera-display feedback computer system, i.e. where the camera of a computer is pointed at the display of the same computer, and create a special space between the camera and display where the physical objects can interact with digital images. For researchers, this setup is particularly interesting because it is a feedback system. And if you remember your control theory classes (or at least the homework that you copied in that class), this setup leads to a stable and inherently interesting systems. This is actual "real" research. Really. The next episode will compare this type of a system to a chromakeying (or bluescreen, or greenscreening) system.

This episodes compares and contrasts the Active Shadows system with a bluescreen (or chromakeying system). Although the segemtnation output of an Active Shadows systems will never beat the output quality of a comparable bluescreening system, the Active Shadows systems allows a person to directly interact with a digital image, instead of a big blue screen. When we create a system such that the digital output of one Active Shadows system is displayed image on another Active Shadows system, we can create an environment for collaborative rich media authoring. In contrast, bluescreening is primarily meant for production and broadcast, and cannot easily integrate a remote presence into its authoring environment PODCAST-HPL-PA-0001-0002 Sat, 26 Nov 2005 19:00:00 GMT 19:11 HP research hewlett-packard labs bluescreening multimedia authoring projector camera Hui Chao Application of Active Shadows for Medical Imaging. This episode shows the application of the Active Shadows algorithm for medical imaging. A doctor or other medical specialist is allowed to add his/her diagnosis on top of medical imaging. The Active Shadows algorithm allows the doctor to directly interact with digital image, seamless capturing valuable personalized information and automatically transforming it into video annotation. The video is an example that is being used in the presentation of the paper, "CMAS, A System for Rich Media Annotation for Medical Imaging." This paper has been accepted to the SPIE 2006 Conference on Medical Imaging. The video was obtain from the site iCardiogram.com. Many thanks to David Reaugh.
