However, based on Shannon entropy, it focuses on the relationships between corresponding individual pixels and not those neighboring pixels. It ignores the spatial information contained in the images such as edges and corners that might be useful in the image registration. Thus we propose the adaptation of mutual information measure which incorporates the spatial information by combining intensity and gradient information. Mutual information value now is calculated from the gradient value and intensity value of the images. Salient pixels in the regions with high gradient value contribute more in the estimation of mutual information of image pairs being registered. Results of normalized mutual information, gradient-based mutual information and new proposed method are presented for rigid registration of medical images. We show that the new method yield better registration accuracy and it is more robust to noise than normalized mutual information. 2012-10-18T08:44:23Z 2012-10-18T08:44:23Z 2012-02-27 Working Paper p. 368-372 978-145771989-9 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6179040 http://hdl.handle.net/123456789/21429 en Proceedings of the International Conference on Biomedical Engineering (ICoBE 2012) Institute of Electrical and Electronics Engineers (IEEE)
