OpenCV Python (Image Masking using Inpaint Function) Please help!! SEEKING EXPERIENCED TUTOR WHO HAS EXPERIENCE WORKING WITH OPENCV PYTHON BINDINGS!!!!

I am using Python IDLE to edit and run script...

I need help with modifying the following inprint.py program, so when a user press 'r' the program
masks the image and produces output which is the image in black and white and only the masked area
is in color...

The program is as follows:


#!/usr/bin/env python

'''
Inpainting sample.

Inpainting repairs damage to images by floodfilling
the damage with surrounding image areas.

Usage:
inpaint.py [<image>]

Keys:
SPACE - inpaint
r - reset the inpainting mask
ESC - exit

cv2.imshow('inpaint', res)
if ch == ord('r'):
img_mark[:] = img
mark[:] = 0
sketch.show()
