Hello,
Maybe this is not relevant, but if the green region is garanteed to be
always simply connected, you just have to fill holes in your
absdiff(G,B) image (imfill function in IPCV).

Dear Scilab community,
Thanks to Antoine's functions I am able to read tif-files as M x N x
Channel - matrix.
Px values are:
red => 255, 0, 0
green => 0, 255, 0
black => 0, 0, 0
white => 255, 255, 255
Now: I want to only keep the green pixel values.
This can be done due to: G = img(:,:,2);
However, this plane does also include the white pixels, since white
has a pixel value of 255 in the green plane.
This is Ok, as long as the white pixels are surrounded by the green area.
However there are also white pixels in the red and black area.
These white pixels should be set to 0.
I started to work with differential images , but somehow I can not get
around the problem.
Please find below an example of my output.
upper line: RGB; R-plane; G-plane ; B-plane
As you can see, the G-plane contains white pixel (2 dots), which are
within the red-area
The desired output would be to have the G-plane without the 2 dots.
Any Idea?
Best Regards,
Philipp
