Is there a way where i can match some sort of screenshots with earlier stored images in my system. Consider 2 images i want to compare A and B. A is full screenshot of monitor whereas B corresponds to a particular window say a small image. My problem is to find whether A contains B or not?

There doesn't seem to be a whole lot out there in terms of Java stuff that does image matching. I've found (maybe) a starting point for you, but be aware that this is a really complex topic. Related StackOverflow topic here.

For image processing I suggest using OpenCV library to get started. It has feature detectors which you can use to detect and find similar objects within an image like this. There are quite a few examples online you can use to perform the function you need. It is a pretty big topic so I can't share a lot, but I hope this can give you a head start :)
