Extract individual planes from an MxNx3 image, or from an axis containing an MxNx3 image.
[R,G,B] = getImagePlanes(I)
Extracts the individual (color) planes from the MxNx3 image specified in I. I may be an image or an axes containing a single MXNx3 image.
I (finally) grew tired of typing:
r = img(:,:,1);
g = img(:,:,2);
b = img(:,:,3);
Now, it's just:
[r,g,b] = getImagePlanes(img);
[r,g,b] = getImagePlanes(gca);
instead! Simple, but useful!
