Compare two images, but gently

Post by zwokaros » 2018-10-16T01:00:40-07:00

Hello

I'm not sure how to explain this but I'll try my best

I have a two lists of slightly different images
(both lists are images of a website with css animations started at the same time and you almost can't tell the difference with the naked eye)

So I tried the compare feature, and it worked wonderful

But is there a way to only get BIG differences between two images?

Here is an example of two images:

The first one

The second one

The difference I get

Thanks

Some comparison metrics can use fuzz:

Code: Select all

compare -metric AE -fuzz 2% redcar1.jpg redcar2.jpg out.png
