Translation Robust Image Registration Method Based on Analytic Wavelet

This paper studies the mechanism how image translation affects image registration algorithms to improve their robustness. The relationships of the subband correlation functions among the scales are derived. The analytical result shows that the aliases of the correlation functions are mainly responsible for the translation sensitivity. An analytic-wavelet-based algorithm is proposed to solve this problem. Theoretic analysis demonstrates that the method is robust against image translation. The effectiveness o...
