Matlab code of unsupervised evaluation method to evaluate segmented image.

I am currently doing image segmentation assessment, which is divided into two methods: supervised evaluation and unsupervised evaluation. But I can't find the code for unsupervised evaluation. Can someone help me? I looked at the 'Image segmentation evaluation: A survey of unsupervised methods', but I can't implement the indicators inside.

In words, explain what is the difference between supervised and unsupervised evaluation.

[lytx]

About supervised we can use groundTruth and compare the segmentation result with groundTruth.But unsupervised evaluation we can't.

[Image Analyst]

If unsupervised evaluation does not compare actual segmentation to the ground truth, then what reference image DOES it compare your test segmentation image to???

[lytx]

I suggest you refer to the literature I mentioned at the beginning. Unsupervised is to use some standard indicators that people generally agree with, or to refer to the original image to calculate the results.

My current problem is that I can't write the relevant code.

All basics methods related to unsupervised methods, like thresholding, othsh's threshold, watershed, MICO and many more followed by morphological operations. Requested you to follow Book: Digital Imge Processing with Matlab by Gonzalez

Thank you for your answer, I have read this book, but I don't find the code I want .The book introduces the basics, I can't edit the code myself.
