[ptx] image registration for HDR generation

[Pablo d'Angelo]

Hi all,

I have just received the following email, which might be useful for people
playing with HDR panoramas.

Hi there,

I've been hacking away on a Perl script that does automatic image
registration and optionally corrects weird EXIF headers.

For the script, dependencies, and a tutorial, please see:
http://www.luxal.eu/resources/hdr/hdrprep/index.shtml

The EXIF stuff is essentially the same code as in WebHDR, so for a list
of supported cameras, please visit:
http://luminance.londonmet.ac.uk/webhdr/cameras.shtml (a bit slow...)
Feel free to upload an image of you own cam if it isn't yet listed.

Hope you find it useful.
