+Interactive Image Segmentation using GrabCut algorithm.
+This sample shows interactive image segmentation using grabcut algorithm.
+USAGE:
+    python grabcut.py <filename>
+README FIRST:
+    Two windows will show up, one for input and one for output.
+    At first, in input window, draw a rectangle around the object using the
+right mouse button. Then press 'n' to segment the object (once or a few times)
+For any finer touch-ups, you can press any of the keys below and draw lines on
+the areas you want. Then again press 'n' to update the output.
+Key '0' - To select areas of sure background
+Key '1' - To select areas of sure foreground
+Key '2' - To select areas of probable background
+Key '3' - To select areas of probable foreground
+Key 'n' - To update the segmentation
+Key 'r' - To reset the setup
+Key 's' - To save the results
