Image registration of medical images
2017 Intelligent Systems and Computer Vision (ISCV), 2017Image registration is a vital problem in medical imaging. It has many potential applications in clinical diagnosis (e.g. diagnosis of cardiac, retinal, pelvic, renal, abdomen, liver and tissue disorders). In this paper a new technique has been proposed based on feature based image registration using SURF (Speeded up robust features) and Hessian matrix ...

Towards efficient registration of medical images
Computerized Medical Imaging and Graphics, 2007In this paper we propose a Bayesian based mutual information technique for image registration, combined with an established affine transformation model. Classical affine models allow the images to be approximately aligned. However, inefficiency and inaccuracy has appeared when using these affine models in rigorous circumstances, such as low-resolution ...

Graphics applied to medical image registration
IEEE Computer Graphics and Applications, 1991Software that has been developed to automate and standardize comparison of 3D images is discussed. The major approaches to image registration are examined. The authors' registration and reconstruction software is described. Studies carried out to determine the relative accuracy of the present registration methods are reported.

Morphological registration of 3D medical images
Proceedings of 3rd IEEE International Conference on Image Processing, 2002Registration of three-dimensional medical image modalities (PET and MRI) of the human brain is performed by a multi-scale morphological shape description combined with 3D Chamfer matching. Objects of Interest are first segmented. For MR images of the head, a Directional Watershed algorithm is used to obtain an accurate segmentation of the brain.

Function Approximation for Medical Image Registration
2018 41st International Conference on Telecommunications and Signal Processing (TSP), 2018Evolutionary computation has been widely used in intensity-based medical image registration due to its ability to deal with the large number of the local minima which the conventional optimization methods fail. Despite this successful application, they still have certain disadvantages, the most important being the need to do repetitive evaluations of ...

Fusion for registration of medical images-a study
32nd Applied Imagery Pattern Recognition Workshop, 2003. Proceedings., 2004The paper is a study demonstrating the application of discrete multiwavelets in medical image registration. The idea is to improve the image content by fusing images like MRI, CT and SPECT images, so as to provide more information to the doctor. The process of fusion is not new but here the results of study have been compared with the results from FCM ...

A Hybrid Algorithm for Medical Image Registration
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005Registration is a process to align different acquired images of the same subject. A major problem in this field is to register images captured by different imaging systems. These images have different gray values so simple methods like correlation are not applicable. In this paper automated registration of CT and MR head images is studied.

Intensity-based registration of medical images
International Journal of Computational Vision and Robotics, 2016Mutual information is used widely as a similarity measure for registration of images. In order to improve the robustness of this similarity measure, spatial information is combined with normalised mutual information. In this paper, mutual information is multiplied with a gradient term to integrate spatial information with mutual information and this is
