A Multi-imager Camera for Variable-Definition Video (XDTV)

چکیده
The enabling technologies of increasing PC bus bandwidth, multicore processors, and advanced graphics processors combined with a high-performance multi-image camera system are leading to new ways of considering video. We describe scalable varied-resolution video capture, presenting a novel method of generating multi-resolution dialable-shape panoramas, a line-based calibration method that achieves optimal multi-imager global registration across possibly disjoint views, and a technique for recasting mosaicking homographies for arbitrary planes. Results show synthesis of a 7.5 megapixel (MP) video stream from 22 synchronized uncompressed imagers operating at 30 Hz on a single PC.

Reinterpretable Imager: Towards Variable Post-Capture Space, Angle and Time Resolution in Photography
We describe a novel multiplexing approach to achieve tradeoffs in space, angle and time resolution in photography. We explore the problem of mapping useful subsets of time-varying 4D lightfields in a single snapshot. Our design is based on using a dynamic mask in the aperture and a static mask close to the sensor. The key idea is to exploit scene-specific redundancy along spatial, angular and t...

Background and Aim: Vascular imaging during surgical procedures is very important and has many applications. There are several methods for intraoperative vascular assessment such as intraoperative angiography, Doppler, and fluorescence-based techniques. The latter group and specially the Indocyanine Green (ICG) Video Angiography (VA) is commonly used for vascular surgery and sentinel node...

The GI-Eye GPS/inertial video system is design to support rapid collection and location of target coordinates through processing georeferenced digital video imager. Extracting coordinates from video imagery has historically required significant processing to determine the relative position and orientation of stereo image pairs (through photogrammetry) or the use of expensive fixedbase stereo vi...
