A comparative analysis of algorithms for fast computation of Zernike moments
TL;DR: A new technique, denoted as q -recursive method, is proposed, specifically for fast computation of Zernike moments, which uses radial polynomials of fixed order p with a varying index q to compute ZERNike moments.

Translation invariants of Zernike moments
TL;DR: A mathematical framework for the derivation of translation invariants of radial moments defined in polar form is presented, using a direct application of this framework, and translation invariant functions of Zernike moments are derived algebraically from the corresponding central moments.

The scale invariants of pseudo-Zernike moments
TL;DR: A mathematical framework to derive a new set of scale invariants of pseudo- Zernike moments based on pseudo-Zernike polynomials that remain unchanged under equal-shape expansion, contraction and reflection of the original image.

Image encryption method based on chaotic fuzzy cellular neural networks
TL;DR: Evaluations on standard test images verified and confirmed that the proposed encryption method is robust against plaintext-only (i.e., brutal force) and chosen-plaintext attacks.
