o presume that i have an part of a spiral, which more or less approximates a logarithmic spiral for a part of a whorl...
Is there a way to construct 2 tangents to this curve and find out where their two orthogonals intersect to become the (local) pole of the spiral with matlab...
At this point i fit a circle to the outline to become the "curvature" (the curvature of a small part can be approximated by fitting a circle into it) radius and centre...
