Looking for Matlab code of unsupervised evaluation method to evaluate segmented image.

I also doing similar thing.My research start with image segmentation.I chose OTSU method to segment all the images and easily for me to find codes in matlab because it already provided.But,my current problem is,I want to evaluate the segmentation result using unsupervised method(ex:NU,SM,E,F) using Matlab.Can anyone here help me with the codes.I cannot find it.Please anyone help me~

I have never heard of NU, SM, E, or F either. Are you referencing the following paper?

Zhang H et al (2008) Image segmentation evaluation: a survey of unsupervised methods. Computer Vision and Image Understanding

If so, you should know that those method names are not universal. I'll look more into that paper to see if I can help...or perhaps Image Analyst can add more insight.

Yup..this paper is one of my reference. What do u mean by "those methods are not universal"?

[Image Analyst]

I don't know what those methods are. Evidently no one else does either since you couldn't find anything on them. For example, what is the "E" method? Otsu is an unsupervised method, and a not very smart one. It's best used in high contrast objects on a uniform background. I find it's rarely, if ever, useful for me.

Do u have any better suggestion for me?Because i want to segment images with white background only. All images that i have were product image like u can see in Amazon.com.

For the evaluation,that is what i got from the paper stated by Matt above. What is the common image segmentation evaluation used in Matlab?
