Marking the difference between 2 images with rectangle - Java

Hi,

I'm pretty new at OpenCV, and been trying to find the most efficient way to mark the difference between two images using rectangle in Java.

maybe you need a better explanation for "the difference of 2 images". (what are you trying to achieve ?)

I uploaded two images: Image 1 Image 2

The difference I'm trying to catch is that, the second image has a small red line, which I want to mark with the rectangle. Thanks.
