Programming Assignment P1: IMAGE MOSAICING

This second handout on assignment P1 explains extra credit options:

• Make the registration process interactive. On a fast graphics workstation, such as an SGI with Reality Engine graphics, you could exploit the real time texture mapping hardware and make it real zippy. A nice general technique for controlling projection parameters interactively is described by Gleicher and Witkin.

• Do automatic registration, as described by Szeliski & Coughlan, Mann and Picard, or your own method. See additional notes on mosaic work too.

• Use high quality resampling filters to get top quality images. See pp. 41-60 of my master's thesis, Fundamentals of Texture Mapping and Image Warping.

• Generate an entire panorama (360 degrees). Your final result won't fit in a single perspective projection, obviously, so use a cylindrical, spherical, or cubical projection of some sort (maybe you could even put it in Quicktime VR format?).
