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.
