According to some embodiments, a set of images may be determined,
including at least one training image and at least one image to be
provided to a viewer. A reduced training image may be created based on
the training image, and at least one enlarging parameter may be
calculated based on a portion of the training image and a corresponding
portion of the reduced training image. The enlarging parameter may then
be used to facilitate an enlargement of a reduced image to be provided to
the viewer.
