Multi-modal 3d Image Registration Using the Kullback-leibler Distance
نویسنده
چکیده
In this paper we address the problem of multi-modal coregistration of medical 3D images. Several techniques for the rigid registration of multi-modal images have been developed; in one of those the Kullback-Leibler distance is used to align 2D-3D angiographic images [1]. In this paper we refine this technique and investigate its performance on the registration of pairs of 3D CT/US images. We test the method with regard to accuracy of registration, robustness with regard to the starting point, and speed of convergence, and obtain promising results.

متن کاملMulti-modal Image Registration by Minimising Kullback-Leibler Distance
In this paper, we propose a multi-modal image registration method based on the a priori knowledge of the expected joint intensity distribution estimated from aligned training images. The goal of the registration is to find the optimal transformation such that the discrepancy between the expected and the observed joint intensity distributions is minimised. The difference between distributions is...
متن کاملRobust Multi-modal Image Registration Based on Prior Joint Intensity Distributions and Minimization of Kullback-Leibler Distance
Robust registration is essential for image-guided therapy as well as structural and functional analysis. In this work, we present a new method that can give superior robustness in multi-modal image registration. This method is based on the a priori knowledge of the joint intensity distributions between image pairs at different image resolutions and the Kullback-Leibler distance (KLD) similarity...
متن کاملMulti-modal image registration by minimizing Kullback-Leibler distance between expected and observed joint class histograms
In this paper, we present a new multimodal image registration method based on the a priori knowledge of the class label mappings between two segmented input images. A joint class histogram between the image pairs is estimated by assigning each bin value equal to the total number of occurrences of the corresponding class label pairs. The discrepancy between the observed and expected joint class ...
متن کاملLearning Based Non-rigid Multi-modal Image Registration Using Kullback-Leibler Divergence
The need for non-rigid multi-modal registration is becoming increasingly common for many clinical applications. To date, however, existing proposed techniques remain as largely academic research effort with very few methods being validated for clinical product use. It has been suggested by Crum et al. that the context-free nature of these methods is one of the main limitations and that moving t...
