I am looking for easy to use software that works on OS X and can "re-center" an equal-area projection fisheye image.
What do I mean by "re-center"? The perspective correction tools built into many software essentially compute what the image would have looked like if the camera had pointed in a different direction. I am looking for the equivalent operation for fisheye images. I want to do this without changing the projection.
I know that Hugin can do this, but there are no binaries for the last two versions and the version before that is awfully crashy.
