below is my binary pic after processing on android platform:

now i want the distance between the two red lines (red lines are added by my mspainter).

would anyone like to give me some tips ? that would be very thankful !

after eroded 5 times and dilated 5 times i got a better pic below , it costs some details (like armpit) ，but sort of could being accepted yet.

        } else {

            //re-count if less than 6 "transfer points"
