need help creating a 2D matrix of an image

i have an ycbcr image and i want to get the cb cr planes in a single 2d matrix .

Y=ycbcr(:,:,1);
Cb=ycbcr(:,:,2);
Cr=ycbcr(:,:,3);

by this im getting three 1d matrices but i want to get the color information i.e cbcr planes in a single 2d matrix.

Please show us the output of

size(ycbcr)

That doesn't make sense to me. You have everything you need. For a given pixel at a given (row, column) you have all three component's values. What is this other thing you're trying to derive, why do you want it, and why would it be more useful than the 3D color image?

its 3 D info

now im not sure, but i think this is what you want:

Y=zeros(size(ycbcr(:,:,1))); %

Y=ycbcr(:,:,1);

Cb=zeros(size(ycbcr(:,:,2))); 

Cb=ycbcr(:,:,2);

Cr=zeros(size(ycbcr(:,:,3))); 

Cr=ycbcr(:,:,3);

i've made 3 different empty mattrix assignments just to be explicit all the 3rd dimensions should have the same row,col size.

I want to find matrix of 0's and 1's (for white and black pixels) for a given binary image

Please start your own thread rather than adding on to all these other threads, and post your image and state what you want the binary image to represent.
