[comp.graphics] origin trans of scaned image

mwg@cadre.dsl.PITTSBURGH.EDU (Mike W. Groff) (06/22/89)

	I will be scanning in several hundred images into a computer.  I
have a reference diagram that divides the screen up into 14 parts. 
The problem is to determine how much of our scanned image overlaps
each of the 14 regions of the reference diagram.
	I would like the algorithm I use to adjust for the fact that each
image to be scanned might not be placed in the exact same position on
the scanner.
	If you have any idea how to solve this problem please send mail.  I
will post to the net if there is demand.  If there is commercially
available software that will help I will try to get a hold of it.  If
your suggestion is in the form of an algorithm, please reference the
hardware you envision it being executed on.
