Hi all,
I have a 4-channel image (.png, .tif) like this one:
And I would like to add padding of type BORDER_REFLECT
around the flower. copyMakeBorder
is not useful, since it will add padding to the edges of the image.
I can add certain padding if I split the image in bgr + alpha and apply dilate
with BORDER_REFLECT
option on the bgr image, but that solution spoils all the pixels of the flower.
Is there any way to perform a selective BORDER_REFLECT
padding addition on a ROI defined by a binary mask?
Thanks in advance.
