Paper Abstract

Multiple image registration plays a crucial role in multiple-sensor or multiple-spectral image fusion. We present an improved multi-resolutional SSDA that bases on wavelet decomposition. When computing the alignment parameters, we use a coarse-to-fine updating strategy and proper preprocessing stage. This approach yields sub-pixel accuracy to multi-spectral images with 2D geometric transformation of translations, rotations and scale changes. Experiment results show that our improved implement is robust and reliable for multispectral images.
