Hi,
In the definition of , i think that the term should be replaced by . Could someone else confirm there is an issue in the definition of ? J.F. 77.194.224.177 (talk) 15:12, 6 June 2008 (UTC)
There are quite a lot of errors in this page. The restriction on the (n,m) pairs
for which the polynomials are defined should be not only that |m|<=n but also
that n-m is even, the polynomial for R should be a sum over only even values of
s in that range, the formula for the coefficients D is wrong, and most of the example
polynomials need deleting or correcting.Fathead99 (talk) 15:00, 6 June 2011 (UTC)
- "On image analysis by the methods of moments" states that unlike for the Zernike radial polynomials, which are defined for |m|<=n only where n-m is even, pseudo-Zernike radial polynomials are defined for |m|<=n with no additional conditions on n-m. Cafet (talk) 20:11, 13 December 2011 (UTC)
I'm not sure how to correct it, but the proper link for the refernce to "An Efficient Algorithm for Fast Computation of Pseudo-Zernike Moments" is: http://ir.canterbury.ac.nz/bitstream/10092/448/1/12584534_ivcnz01.pdf —Preceding unsigned comment added by 147.197.140.136 (talk) 09:39, 24 November 2009 (UTC)
Used in Optics ?
editI am an optical engineer and I have never heard of anyone using these "pseudo" Zernike polynomials. We use the Zernike polynomials, which are not defined the same way have their own page on wikipedia: https://en.wikipedia.org/wiki/Zernike_polynomials. I think that assertion needs a reference. — Preceding unsigned comment added by 212.203.64.194 (talk) 16:31, 6 October 2016 (UTC)
Original Definition of the pseudo-Zernike Polynomials
editThe pseudo-Zernike polynomials is similar than the Zernike polynomials. The differences between them are two. These was derived by Bhatia and Wolf [1]. The first is that it must to eliminate the condition n − |m| = even regarding the Zernike polynomials. The second is that the radial polynomial equation changes slightly from the Zernike polynomials. Since the set of pseudo-Zernike orthogonal polynomials is analogous to that of Zernike polynomials, most of the previous discussion for the Zernike Moments(ZM) can be adapted to the case of pseudo-Zernike Moments (PZM).
