Hi friends!I am writing a paper on segmentation methods.I need to apply the segmentation technique to a radiographic image. The size of the image is too large(5000*7000). Can you suggest me some methods so that I can get the result fastly?

imresize() will make the image smaller, if that's what you want.

You need to have some "ground truth" - in other words, the known, true, accurate segmentation. What/who can you trust to give you the ground truth? Would you trust a physician if they outlined the region and said "I know for a fact that this is the most accurate boundary for this tissue"? If so, then that's your ground truth and you need to compare all your algorithms against that.
Also, please look at this: http://sve.loni.ucla.edu/instructions/metrics/?wscr=1920x1200 and study up on ROC curves ( http://en.wikipedia.org/wiki/Receiver_operating_characteristic
