“…Thus, moments of different orders correspond to independent characteristics of the image [25]. An accurate representation of a PSF can then be achieved by using Zernike moments, since they offer a compact representation where low-order coefficients represent typical aberrations, while noise is represented in higher order coefficients [26]. Zernike moments are based on a set of complete and orthogonal functions defined over a polar coordinate space, inside a unit circle.…”
