Image::Compare::AVG_THUserOContributed Perl DoImage::Compare::AVG_THRESHOLD(3)

       Image::Compare::AVG_THRESHOLD - Compare two images by the overall
       average color difference	of their pixels.

       See the docs for	Image::Compare for details on how to use this module.
       Further documentation is	meant for those	modifying or subclassing this
       comparator.  See	the documentation in Image::Compare::Comparator	for
       general information about making	your own comparator subclasses.

       accumulate(\@pixel1, \@pixel2, $x, $y)
	   This	method is called for each pixel	in the two images to be
	   compared.  The difference between each pair of pictures is
	   collected and stored	for later use by get_result().	This method
	   never short-circuits; when this comparator is used, all pixels are
	   compared, every time.

	   Returns either the median or	the arithmetic mean of the values
	   collected by	accumulate(), depending	on the average type provided
	   when	this object was	constructed.
