If you have an image that you could provide as an example, please insert it into your question using the image tool/icon (don't forget to click on [Insert Image] after you have chosen it).

regionprops() requesting the Perimeter value?

When you used the major axis length, what part did you find was "not working" ?

It seems as though you're up and running with major axis length (since you accepted that answer), but I'd do it differently. MajorAxisLength will give you the length of an ellipse fitted to your blob. If you want the actual length between the two farthest points, then you need to call bwboundaries() and compute all the distances and take the longest one. I do that in my attached demo. There is no built in function or option of MATLAB or regionprops() to do that, that's why I had to write it myself.

Who are you talking to? What code? I attached my code. Code that does what?
