well I just was wondering if someone could give a visual representation of the polynome. In mathworld the expression of the first polynome are given.
It has been used in machine vision to obtain invariant features (rotation and translation and reflexion invariant) under the name of Zernike moment. That why I would be interested in being able to visualize them to understand from where these invariance properties are coming from. They are apparently good because the lower moments (under degree 4) are alledgedly robust to noise and they provide low information redundancy.
