Rendering with Inverse Concentric Mosaics

In this paper, we describe an image-based rendering technique called Inverse Concentric Mosaics (ICM), which is based on Concentric Mosaics (CM) (H.-Y. Shum and L.-W. He, 1999). While CMs allow scenes to be viewed from inside looking out, ICM permits the user to visualize objects from the outside looking in. ICM has the following advantages: viewpoints of objects can be changed in a continuous manner and at interactive speeds, photometric effects, if any, can be captured (enabling photorealism), and the image database can be easily acquired and processed. We show examples for synthetic and real objects.
