	       A Survey of Image-based Rendering Techniques

In this  talk,   I will survey  the   techniques for  image-based rendering
(IBR). In contrast  with the conventional  approach of using 3-D models for
creating new virtual views, IBR techniques require only the original images
to produce new virtual views. I've divided these techniques into four basic
categories,     namely  non-physically  based    image  mapping, mosaicing,
interpolation   from    dense  samples,   and   geometrically-valid   pixel
reprojection. This division is based  primarily on the  nature of the pixel
indexing scheme.   I   will discuss the characteristics  of   each of these
categories and present  representative techniques. I will  also touch on  a
couple of  my recent projects  in IBR.  It  is interesting to note that IBR
has  evolved to be  an  area that has  generated  active interest from both
computer vision and computer graphics communities.
