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"
