In this paper, we present a translation and scale invariant
descriptor. Orientation invariance can be achieved by measuring angles at each point relative to the direction of the
tangent at that point as in Shapes Context or applying the
Fourier Transform [3]. In this work, we have decided to avoid
significant orientation invariance since the word matching
and recognition task does not tolerate high variance in the
orientation of compared shapes, see the case of digits 060 and
090.
