extraction of pixel values of image

Hello

i want to extract the pixels values of image attached and store it in array or matrix?

[Adam]

Where does the image come from? Didn't it start out in a matrix before it was an image?

[Guillaume]

The question is not clear. In matlab, an image is stored as a matrix of pixel values. So if you've got the image loaded in matlab, you already have what you want.

>> a=imread('image.jpeg');

>> read1=a(:,:,1);

>> green1=a(:,:,2);

>> blue1=a(:,:,3);

[Guillaume]

Avoid using clear all or even clear (which is not as destructive). Let the person decide whether or not they want to loose all their workspace variables.

I would recommend a much more meaningful variable name to store the image.

read is a built-in function. You shouldn't use built-in function names as variables -- I think you meant red.
