I have an masked hand image using skin color detection, and the main outer shape is pretty complete. But how should I go about removing the internal parts? I've tried morphological closing, erosion, dilation to no avail. I also don't want to tinker with the skin color parameters.

  • @chintogtokh See the answer [here](http://stackoverflow.com/questions/22427550/face-mask-in-opencv) – Haris Apr 15 '14 at 10:14
  • Thanks for that. The second method is easier to implement, I guess, what with OpenCV's floodfill mask needing to be a different size from the source image. – chintogtokh Apr 15 '14 at 11:41
