i have a image file of a welded metal in jpg format. In the image ,the defect in welding appears as an object having maximum intensity.I need a code that can convert the coordinates having intensity above a certain given threshold to '1' and all other points below threshold to '0'. please help. thanks

If "I" is your intensity image and your threshold is stored in "thresh" pretty much all you need to do is:
mask= I>Thresh
Mask would have 1 for every pixel that has the intensity more than the threshold and the rest would be zero.

This (color tracking) seems like enough of a different question that it should be on its own, rather than as part of this one on thresholding, which has already been marked as solved. Please make a new question and post an image.

This is just what my Image Segmentation Tutorial does. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Then it goes beyond that - it also finds centroid, area, etc. and crops out the regions. Adapt it as needed.
