NAME

Image::Compare::THRESHOLD_COUNT - Count the number of pixel pairs in two images that differ by more than a given threshold.

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

get_result(): Returns the count of pixels pairs whose difference exceeded the threshold.
setup($img1, $img2): Sets up the collection variable for the count to be returned.
