Autopano-sift-C

autopano-sift-C is a C port of the C# software autopano-sift. It is somewhat faster and doesn't require a C# runtime - Installing the mono C# runtime on OS X has proved to be problematic on some systems.

Additionally, autopano-sift-C has experimental modifications to perform feature identification in conformal image space, this helps with wide angle or fisheye Projection photographs.

autopano-sift-C is available from the hugin project.
