Thread Subject: Comparaing Jpeg or DICOM images to detect differences or motion

Hello,

I'm new to Matlab and never use it. So I'll appreciate a first aid in telling me what to install/use to try getting to a result.
My aim is performing a proof of concept for the follwing:
I have X-Ray images in JPEG or DICOM format. Different images of the same body, at same position are taken at various consequtive moments. I can do it at 30fps but estimated that it's not useful. I did it with greater intervals.
The proof of concept I would like to do is for example to compare 2 or many consecutive images of the same position in order detect any difference. Ultimately, my goal is to detect if there is an activity (motion) and where.

I appreciate if someone can advise in saying what should I install, which function to try, etc. I would be glad to share more details about the topic later on.

Thanks in advance.
