Image::Compare::AVG_THUserOContributed Perl DoImage::Compare::AVG_THRESHOLD(3) NAME Image::Compare::AVG_THRESHOLD - Compare two images by the overall average color difference of their pixels. OVERVIEW 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. METHODS 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. $cmp->get_result() 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.
