-A custom pattern class that can be used to calibrate a camera and to further track the translation and rotation of the pattern.
+A custom pattern class that can be used to calibrate a camera and to further track the translation and rotation of the pattern. Defaultly it uses an ``ORB`` feature detector and a ``BruteForce-Hamming(2)`` descriptor matcher to find the location of the pattern feature points that will subsequently be used for calibration.
