Depends on the format. Maybe you can use dicomread(). But somehow you need to get a reader for your data files. I don't have one.

This is done in my image Segmentation Tutorial with coins. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
Just ask regionprops to get the area and 'EquivDiameter'
measurements = regionprops(CC, 'Area', 'EquivDiameter');

- My demo shows you how to select certain blobs based on some criteria like area. Did you see that code?
- I'm not sure what you're asking. What is "4 values of connected components". I show you how to get the connected components, labeled image and display it in both grayscale and with different colors for each individual blob. What do you want and why isn't my code doing it?
