I have one algorithm that works good for images with relatively uniform background. For example, it would work great for contrasting images of eye retina. What kind of images do you need to work with?

There are a variety of ways to find a threshold, from the Otsu method (bwthresh) to the triangle method, to an interactive manual method that I've uploaded to http://www.mathworks.com/matlabcentral/fileexchange/29372-thresholding-an-image

My email is just a spam catcher account. I can't reply or accept attachments. Post your image to tinypic.com. Have you tried adpathisteq? After doing that you can use a global threshold but it would have the effect of a local threshold since the output image has its output value adjusted for every pixel.
