[ptx] autopano-sift 2.4, libsift 1.8 released.

[Sebastian Nowozin]

Hello everybody,

I am pleased to announce a new version of autopano-sift and libsift.  The
changes are the following:


autopano-sift 2.4, libsift 1.8
2005/10/31, the "long overdue fix release"

  * Fix a serious bug in the Gaussian sigma computation, spotted by Liu Rujie
    (rjliu at frdc dot fujitsu dot com).
  * Fix bug in the DoG scale handling of libsift.  Thanks to Donovan Parks
    (donovan dot parks at gmail dot com) for spotting and reporting it.
  * Fix ","/"." locale-dependent issue in control point output.  Thanks to
    Eugenio Milano (eugenio_milano at yahoo dot it) for reporting the issue.
  * Add "bin_install" target to the default "all" Makefile target and remove
    the erronous "bin" target.  This caused troubles downstream, when people
    forgot to explicitly add the "bin" target as well, which messed with make
    as bin/ is also a directory.


It is purely a bugfix release.  If version 2.3 works well for you, there is no
reason to upgrade quickly.

If you are interested in the SIFT internals and the like, there has been a
serious fix to the scale space Gaussian convolution process.  The incremental
convolution sigma has been wrong and is now believed to be fixed.


Regards,
Sebastian
