I'm new to the OpenCV. I want to find the difference area in the two images.

C:\fakepath\image1.png

C:\fakepath\image2.png

In the attached images, i need to find the different area i.e, the small circle coordinates.

Please guide me to do it.

Thanks.

hi try thing:

Mat image1=imread("1.png");     
Mat image2=imread("2.png");     
Mat result=image1-image2;

and you can get this image as result

then maybe look up some findcontour function to find area center

something like this , maybe in different program language but similar.
