How to combine this R, G, B values of an image so that i have an image?

I have R,G,B values of an image separately. I need it as a single image.Can anyone tell how to put these values in a single matrix, so that i have a single image.

Answer 1

your_image = cat(3,R,G,B);

Thank You :-)

Answer 2

Assuming your R,G,B values are MxN arrays, then you need to stack them into an MxNx3 array.

You can do this with the cat() command:

>> RGB = cat(3,R,G,B);

You can display the resulting array with the image() command

>> image(RGB)

Thank You :-)
