Imago-Based Bondoring:A Now Interface Between Computer Vision and Computar graphics LeonardMcMillan MIT Steven Gortler Harvard University W h a t is IBR? Image-based rendering (IBR) describes a set of techniques that allow three-dimensional graphical inter'action with objects and scenes whose original specification began as images or photographs. In an IBR pipeline, processing is applied to a set of input photographs creating an intermediate data structure. Later, this data structure is used to create new images of the scene or object. Computer vision provides tools to analyze Images and create models representing shape and surface properties. Computer graphics provides cools to take models and create images. This suggests t h a t image-based rendering can be achieved by combining computer vision and computer graphics techniques. However, is combining the bestknown computer vision and graphics techniques the best we can do? Many computer vision algorithms are just not very robust, and high quality rendering can be compu=tional!y expensive, To better explore the connection between computer graphics and computer vision we ask the following question. H o w concise a model should one t r y to create from the image data using computer vision analysis?At one extreme, one could ask
