The registration of PP and PS images is a process of correlating corresponding seismic reflections in the two images. We use dynamic image warping to automatically estimate a smooth field of vertical shifts. In warping the PS-image with this shift field, we move reflections in the PS-image to match these in the PP-image. The shift field can also be used to compute the Vp/Vs ratio. Examples for ...

This paper addresses four different aspects of the remote sensing image fusion: i) image fusion method, ii) quality analysis of fusion results, iii) effects of image decomposition level, and iv) importance of image registration. First, a new contourlet-based image fusion method is presented, which is an improvement over the wavelet-based fusion. This fusion method is then utilized withinthe mai...

This paper focuses on finding techniques that can be used in cardiac magnetic resonance images semiautomatic registration in a simple and fast way. The suggested technique depends on using parts of one image selected by the user to be matched with another image of the same patient in order to find control points or correspondences between those two images. The experiment focuses on three techni...

In this article we study the problem of thoracic image registration, in particular the estimation of complex anatomical deformations associated with the breathing cycle. Using the intimate link between the Riemannian geometry of the space of diffeomorphisms and the space of densities, we develop an image registration framework that incorporates both the fundamental law of conservation of mass a...
