Thanks for the help, I'll change the name of the image, just to avoid confusion in the future. In terms of the image that I used, here is link for it: http://drop.io/b2r3eej

In the variable editor it says up as a "a x b" matrix, not a "p x q x r" matrix.

No it doesn't. I downloaded binary.png and it says it is a color
image. It says it's a 322 x 427 x 3 image. I changed your code to
convert it to a monochrome image, and changed the name back to
originalImage instead of Image. Now it works. Fixed code is below:

originalImage = imread('C:\Documents and Settings\tk2013\My Documents
\Temporary stuff\binary.png');
[rows columns numberOfColors] = size(originalImage);
if numberOfColors > 1
originalImage = originalImage(:,:,1);
end
bw = im2bw(originalImage, graythresh(originalImage));
binaryImage = imfill(bw, 'holes');
axis square;
set(gcf, 'Position', get(0, 'ScreenSize'));
% Display the binary image.
labeledImage = bwlabel(bw, 8); % Label each blob so we can make
measurements of it
subplot(3, 3, 4); imagesc(labeledImage); title('Labeled Image, from
bwlabel()'); axis square;
% Get all the blob properties. Can only pass in originalImage in
version R2008a and later.
blobMeasurements = regionprops(labeledImage, originalImage, 'all');

Oh ok, I see. So the problem was that the image was a three dimensional image? How did you convert it to a monochromatic image?
Thanks for all the help so far!

I converted it to a monochrome image by taking the red channel:
originalImage = originalImage(:,:,1);
Since it's just black and white (although it's not binary nor
monochrome) all the color channels are the same so taking the red one
is as good as taking any or as good (but faster) than calling
rgb2ind().

I tried running it, it works, but for some reason, the it only sees 1 blob. There are three distinct blobs in the image and I can't seem to figure out what is wrong. The bwboundaries seems to be working fine, but even in my variable editor, numberofblobs is 1.
