Extracting information from images of different size

Hi everyone, I wanted to conduct an analysis of images (i.e. print ads) that have different size (i.e. in some pictures I need to analyze a certain print ad and not the rest. The goal is to compare the jpeg size of the images or use some visual analysis function (for instance, Canny edge detector, or Feature Congestion). Is it possible to do it?

Thanks in advance

Can you show us pictorial examples?

Of course,

in attach you will find two examples. I want to compare a small ad (it's in the "test" picture) with a full-page ad. The main goal to compare the jpeg or use maybe some kind of visual analysis function with MATLAB.

I think the given ad is not present in the given image. Can you show us an image where the given ad is present.

I opened the links and they show the ads normally. For instance, I want to analzye only one small ad (e.g. bottom-right)
