This software allows you to compare two images using different techniques, giving you the ability to identify differences and similarities between them.
Image::Compare is a Perl module designed to compare two images in different ways. It provides you with a variety of comparison methods that operate on a pixel-by-pixel basis to obtain statistics or data based on color value comparisons. The library heavily relies on the Imager module, which means it's necessary to install Imager to use this module. However, you don't need to know anything about Imager to use the compare functions.
To perform an image comparison, you need to provide three pieces of information: the first image to compare, the second image to compare, and a comparison method. Some comparison methods require extra arguments like boolean value, number or hash reference containing structured data. You can see the documentation below for more information on how to use each comparison method.
Image::Compare offers three different ways to utilize its comparison functionality. You can create an Image::Compare object, call set_* methods to provide it with the necessary information, and then invoke compare() on that object. Alternatively, you can construct the Image::Compare with all pertinent data right from the start, or you can invoke compare() with all the information directly. In the third case, you can either call compare() as a class method or directly invoke the method from the Image::Compare namespace. You can also import the method to your local namespace by passing the word "compare" to the module.
Overall, Image::Compare is a powerful image comparison module that allows you to compare images in a variety of ways without having to know anything about the underlying Imager module.
