How to extract a QR Code

How to extract the QR code from an image? The two images below are provided as references, as I have many images, and the positions of the QR codes vary. Thank you, everyone

@w30290083o9nn – What file format are the originals?

How many images is "many"?

Is there a way to manually sort the images into groups where the QR code is in a similar approximate vertical position? The crop automation can then work out the QR code from the surrounding areas once initial processing is performed based on the rough vertical location.

There are probably hundreds of them, and the position of the QR code on each image is different, so they cannot be cropped in a centralized manner.

Is this spam or do you have some question?

The blue Channel seems to be promising. 

Load as a Selection, Select > Inverse, Quick Mask Mode, Threshold 245, Filter > Other > Minimum, Filter > Other > Maximum, exit Quick Mask Mode, Image > Crop. 

Edit: Forgot to mention that this should be recorded in an Action etc.

Great job, I was looking for a method to isolate the code but it kept on picking up the text.

Could you please send the action file? Thank you.

Extract to what? What output are you looking for, is it a set of images with just the QR code  and everything else trimmed away, or is it a text file with a list of URLs, or something else ?

Keep only the QR code image and crop out the rest.
