PolySamp Clipping resampling

This page contains pointers to information and code for the Polygon Clipping Resampling (PolySamp) algorithm. A PowerPoint poster and links to an implementing Java class are provided. While this class is in the package skyview.geometry it uses no other classes other than the standard Java distribution. However the PolySamp class assumes that the corners of the resampling pixels have been projected into the plane of the original image pixels.

This code is provided as is without warrantee. Please send comments, suggestions, and bug reports (and fixes) to Tom McGlynn.

Note: While I have not been able to find a discussion of the PolySamp algorithm elsewhere, it seems unlikely that this simple method has not been used elsewhere -- in the commercial image processing domain if not in scientific use. Pointers to earlier uses would be welcome.
