Query Regardaing ZernikeFeatureComputer Implementation.

[Devmassnk]

So it is taking too much time to computing higher order zernike moments. Can i pre-calculate the values of all the radial polynomials upto certain degree, order and for a particular image size, as for calculating a radial polynomial for a particular order and degree i just need a order, degree and r(distance from the origin to the given co-ordinates). So i can compute all the values and store in a particular file and whenever i required certain radial polynomial i just need to read from file(without wasting my computation on finding factorials). Is it the right way?
