Hi,
What have you already try?

[kbarni]

HoughCircles or TemplateMatching should work (depending on the needs).

How about FeatureMatching ?
can i get MinMaxLocResult or point (x, y) from MatOfDMatch or DMatch object ?

no, it would work different, you try to get a homography transform between your template an query image, telling you, where the template is (and in which pose / rotation)
