image-diff | Create image differential between two images | Computer Vision library

A better result can be obtained by thresholding the mean of the difference beetween given images.

Well, I 'v figured out how to stop this behavior. after 6 hours of search in the code in theme + WooCommerece plugin code, I found the solution.

1.First copy the file wp-content/plugins/woocommerce/assets/js/frontend/add-to-cart-variation.js To your child theme /woocommerce/js/ folder if not have that folder create one.

2.Paste this at your theme child to call the new file and deregister the default file by woo:

I realized my previous answer was incorrect & overly complicated (It relies on node creation order, also there's no need to add fields to imageSharp nodes. Here's the link if someone's interested.). Here's the better answer:

Since the hero image is always at the same directory as the markdown file, we can simply query it based on its directory.

The problem is that you added a default value to the arguments you add, but didn't set required=False. This means the program will throw an exception when parsing the arguments, unless you invoke it with the actual -f/--first and -s/--second.

The solution is to either:

1. Set required=False in both add_argument calls, since you provide a default. That way, you can call python my_script.py and it will use the default provided.
2. Invoke your program by providing the two CLI options: python my_script. py -f some_file.png -s some_other_file.png

You need to give different names to your agent. So use something like below

You can calculate the Structural Similarity Index between images and based on the score keep or discard an image. There are other measures you can use, but basically a method that returns a score.
