+Robust line fitting.
+==================
+
+Example of using cv2.fitLine function for fitting line to points in presence of outliers.
+
+Usage
+-----
+fitline.py
+
+Switch through different M-estimator functions and see, how well the robust functions
+fit the line even in case of ~50% of outliers.
+
+Keys
+----
+SPACE - generaty random points
+f     - change distance function
+ESC   - exit
