Hi,

you should look for Template Matching. There's a function in Imgproc, called Imgproc.matchTemplate. There's a good explanation for C++ API here: http://docs.opencv.org/doc/tutorials/imgproc/histograms/template_matching/template_matching.html

It should be easy to convert to Java.

Besides, there's some more explanation in chapter 7 of "Learning OpenCV Computer Vision with the OpenCV Library".

Best regards, Daniel
