Learn OpenCV with Python (First Edition Code)

This is the code for the first edition of the book. All contained in this folder was written by Joseph Howse and can be found in its original form at [http://nummist.com/opencv/#book.3923]

I (Joe Minichino - techfort) only updated the code so it is compatible with OpenCV 3, which mostly consisted of the following changes:

1. replace all cv2.cv. occurrences with cv2.
2. replace all call to VideoWriter.retrieve to take no arguments (channel keyword not supported)
3. replace all calls to cv2.Color with cv2.cvtColor
4. replace all calls to cv2.CV_FOURCC with cv2.VideoWriter_fourcc
5. replace the flag cv2.CV_HAAR_SCALE_IMAGE with cv2.CASCADE_SCALE_IMAGE
