Then you will have to write code to determine the coordinates.

Hi Lin,
"How to get the center point?"
  • From the question, it isn't very clear how you define the the image. Have a look at the regionprops function to get the centroid of the image. You could otherwise also simply calculate from the average of the extremeties of the image coordinates.
"How to get the distance from W to other point?"
As previously mentioned on the thread, you may have to programmatically call all these functions on your image set iteratively.
Hope this helps!
