Title: Re-Live the Movie "The Matrix": From Harry Nyquist to Image-Based Rendering

Speaker: Prof. Tsuhan Chen, Department of Electrical and Computer Engineering, Carnegie Mellon University

 

Abstract: In recent years, the field of visual computing has observed a convergence of image processing, computer vision, and computer graphics. Multiview imaging represents one central theme of the convergence. Now widely used in applications ranging from special effects (e.g., in the movie "The Matrix") to 3D object tracking, multiview imaging has become an essential tool for creating informative visualization and effective 3D analysis. In this talk I will introduce recent research on sampling, reconstructing, and relighting multiview images. I will present our mobile camera array, composed of 48 mobile platforms each carrying a video camera. These mobile cameras respond to 3D scenes and position themselves for the most effective 3D analysis. While discussing the mechanism for sampling the 7-dimensional plenoptic function, we will reveal the connection between multiview imaging and the Sampling Theorem discovered by Harry Nyquist almost 80 years ago!
