+# Face detection with ML and Open CV
+
+In order to build face recognition software, we have to use the built-in Haar cascade classifiers in OpenCV. Luckily these classifiers have already been pre-trained to recognize faces!
+
+*images/* folder has several images for face detection. 
+
+One can modify *scaleFactor* and *minNeighbors* parameters to fine tune the face detection technique.
+
+run the command to test it
+
+python detect_faces.py --face cascades/haarcascade_frontalface_default.xml --image images/obama.png
