Image-Based Rendering: Past, Present, and Future Directions
Abstract: In this talk, I will present a collage of recent results from the fledgling field of image-based rendering. Image-based rendering (IBR) is a new class of computer graphics techniques in which collections of images, rather than models of surface geometry and material properties, play the central role of an underlying scene representation. Image-based rendering fundamentally recasts the computational approach to image synthesis from a problem of simulation to a problem of signal reconstruction.
I will discuss a wide range of approaches for synthesizing novel renderings of a scene given a set of images. These include image warping, light fields, visual hulls, and view-dependent texture mapping methods. In addition to describing these image-based rendering techniques, I will also address the complementary problem of IBR model acquisition, and provide several examples of acquisition systems that we have built in our group.
Finally, I will relate IBR to a more general problem of constructing generative models from collections of samples. I will then suggest how the lessons learned from IBR can be reapplied to new problems in computer graphics.
