Keith's Image Stacker is an image processing program for the Macintosh that is oriented primarily toward astrophotography....
What Keith's Image Stacker provides, more than anything else, is a workspace in which to align many similar images (say from a quicktime movie of Jupiter taken through a telescope with a webcam) and then to produce a stack of the images, which consists of a single image that comprises either the sum, or the average, or
some value in between of the individually stacked images. Stacking images is
a well-established method for increasing the signal-to-noise ratio in a
series of similar images. True "information" will shine through the stack,
while random noise will drop out.
(MacOS required, carbon, meaning OS X or any reasonably recent OS 9 or 8)
