There are two results (binary vessel images) obtained from two different methods.
They appear very close (almost the same). So, I expect that their similarity index with Dice, which is calculate by the equation given in http://www.mathworks.com/matlabcentral/answers/68720-dice-similarity-index-between-segmented-image-and-ground-truth
However, their similarity index is very different (0.80 and 0.15)
Why ?

You didn't answer my questions. So post your code and images.

Thank you ImageAnalyst. I could not get permission to upload images, so I could not share it with you. After opening all binary vessel images with bitmap, they are saved as png again. Then I can used the above matlab codes. the problem has been solved by this way Thanks again for your interest
