Hi,
While adding documentation in doc/filters.texi as part of [GSOC]Color
Constancy Filter project, I found the url for xbr filter giving an
internal server error. After some search I found another link where the
author of the filter(and algorithm) posts a tutorial for the algorithm.
This patch update the existing url with the newly found one.
Thanks,
Mina
