http://www.mathworks.com/help/images/ref/bwdistgeodesic.html Let the mask be true only at the "end" of the curve, seed only at the "beginning" of the curve, BW is the curve, then the geodesic would be the shortest "distance" through the curve to get to the end.
http://www.mathworks.com/help/images/ref/bwtraceboundary.html and take number of rows in returned matrix
