Inpainting sample
Usage:
'dilate' bar - Adjust mask to inpaint (Non-black areas indicate the area that needs to be inpainted).
'radius' bar - Adjust radius of a circular neighborhood of each point inpainted.
'n' key - Inpaint using Navier-Stokes based method
't' key - Inpaint using Alexandru Telea's method
'c' key - Clear the inpaint window
'ESC' key - exit"
