In this paper, a number recognition algorithm on Spiral Architecture is developed and experimented.This algorithm uses affine integral invariants with invariant parameterization.It firstly separates the object edge into a few closed boundaries.Each boundary is segmented into a few sections according to their directions (clockwise or anticlockwise) around a common central.Finally, a feature vector rather than a single feature value is computed for each number.This proposed algorithm successfully computes the unique feature vectorsfor ten standard Arabic numerals.Every number can still be distinguished from others even experiencing an affine transformation.
