How about

binaryImage = grayImage > 50; % Or some other value.

You're welcome. What way did you use? I never use im2bw() because it takes thresholds in the range of 0-1 and I find that very inconvenient. I'd rather pass in a gray level but it's not smart enough for that (yet - I'm going to bring it up with them). Internally im2bw ()does what I did. It just has to convert either the threshold to an actual gray level or convert the image to the range 0-1. But then it has to do the thresholding like I did it.

actually i am using the wide line detector code to get the above image. http://www.mathworks.nl/matlabcentral/fileexchange/35754-wide-line-detector So i modified the codes in huang_usage.m in order to get what i want.
