Under what conditions do you want 0 to be generated, and what conditions for 1 ?

binaryImage = logical(yourImage);
yourImage must be an integer (of any type), single, or double array of only 0's and 1's. Any other values (other than 0 or 1) will involve thresholding to make them true or false.

That IS my exact code...and it works. Yours is the code that doesn't work according to your own statement, so doesn't it make sense that it should be you that posts the code that doesn't work?

Well, what is the error?
Anyway, if you read my answer you'd see that it is valid only for images comprised of only 1's and 0's. You probably don't have that. You cannot convert your image into a binary image without thresholding.

Well it's basically an "anything but 0" threshold :)
