Hi,
I want to remove everything with the rgb color (127, 127, 127) from an image. I am using
externalMask = planta.img(:,:,1)==127 & planta.img(:,:,2)==127 &...
planta.img(:,:,3)==127
to know where the grey pixels are.
I want to show the image and that the grey parts doesn't appear.
How can I do that?
Thanks in advance!
PS: I am using R2016a version.

mask = all(planta.img == 127, 3);
image(planta.img, 'AlphaData', 1-mask)
