Gesture Recognition with Next-Generation Webcam

This project presents next-generation webcam hardware and software prototypes. The new prototype webcam has an extremely wider view angle than traditional webcams and can capture stereo movie and high-accuracy depth images simultaneously. Users can chat with stereoscopic video. Accurate depth-image processing can support not only all Kinect scenarios on a PC, but also a gesture-control user interface without a touch screen. Besides computer vision, the webcam includes a hardware accelerator and a new image-sensor design. The cost of the design is similar to that of current webcams, and the webcam potentially could be miniaturized as a mobile camera. The project showcases new user scenarios in playing games with this webcam.

CoDAC: Compressive Depth Acquisition Camera

CoDAC is a new time-of-flight based range measurement system for acquiring depth maps of piecewise-planar scenes with high spatial resolution using a single, omnidirectional, time-resolved photodetector and no scanning components. In contrast with the 2D laser scanning used in LIDAR systems and low-resolution 2D sensor arrays used in TOF cameras, CoDAC demonstrates that it is possible to build a non-scanning range acquisition system with high spatial resolution using only a standard, commercially-available, low-cost photodetector and spatial light modulator.
