A pyramid approach for remote sensing image registration based on mutual information and grey relational analysis is presented. The methodology applies edge information of image extracted using grey relational analysis and combines with mutual information regarding as similarity measure. First, the image pyramid is constructed by wavelet transform, and then coarse-to-fine multi-resolution search approaches...
Wavelet transform has the good characteristic of spatial and frequency locality, but it isnpsilat suitable for describing the signals, which have high dimensional singularities. Curvelet is one of new multiscale transform theories, which possess directionality and anisotropy, and it breaks some inherent limitations of wavelet in representing directions of edges in image. So when the curvelet transform...
Automatic band-to-band registration of multispectral images is the most critical pre-processing requirement for imaging tasks performed on board satellites, such as data fusion, intra-band coding, change detection, spectral signature based classification, etc. The performance of these tasks depends on the robustness and accuracy of band registration. The a priori information of band misalignment is...
