[Scilab-users] using SciCV

[P M]

Dear all,

I read an RGB image with ScCV imread:

img = imread("path_to_image",CV_LOAD_IMAGE_COLOR);

The result is an image of type:  CV_8UC3

I can display the image pixel values with: disp(img)

The image itself is of type: Mat (Mlist)

So far, so clear.

Now, I want to extract a single plane..lets say the R-plane

I would normally do something like this:

R = img( : , : , 1)

But for some reason it does not work.

It seems that one can only extract pixel values from all 3 planes
altogether.....If so, why?

So the question comes down to:   How to extract/change a single pixel
value of a single plane in SciCV ?

Thank you,

Philipp
