Extract plane from a image

[advark]

Hi, can anyone help me with this how can i extract the rgb plane from an image.
I need extract the red,green and blue plane from an image and show them in a vi.
I have a vi that extract the turn into the grayscale from a color image.

On the graphics palette is a color to RGB VI.  Take your 1-D array of image data, autoindex it into a for loop.  Wire out the R, G, B values through an AutoIndex tunnel.  Now you will have a 1-D array for each of those colors of the image data.

I did not understand well, could you explain me better in a vi

Forget that last message.  Color to RGB wasn't doing what I thought it was.  I realized your image data already as the R G B components coming out of your decimate array function.  The 1st 1D array is Red, the 2nd Green, the 3rd Blue.  See the attached block diagram.  If you take the red array and interleave that with two arrays full of zeroes of the same size, you get a red image back.  Likewise for the green and blue 1-D arrays.

could you send me the vi please.

It looks like you are using LV 8.0?

I'm not sure what you are asking by this question.  In the top part of your code, I think you are already doing this.  You are reading the attributes of the image and setting the boundaries of those 2 picture indicators to math.

If this isn't what you want, than please explain what you mean by its "original size".

Hi David,

if you want to have your gray picture in the original size, then you can use the "Interleave 1d Array" function. In gray pictures R,G and B have the same values.

Hope it helps. Mike
