I would like to match two fingerprints using minutiae method. I pre-processed image. From thinned (skeletonized) image, I have extracted minutiae (endings and bifurcation). Now I would like to match them, but I do not know how to calculate orientation angle of minutiae point.

Is there somebody, who can help me, write algorithm or provide existing solution?

Thanks.
