QE SuperResolution is a tool for enhancing the quality and resolution of
images. It is based upon combining image information from several
similar images taken from a movie sequence, or consecutive shots from a
still camera. The software automatically extracts the information about
a particular region of interest from all images, and uses the
information to recreate an image with higher resolution and quality,
compared to any individual image of the sequence.
