Book excerpt: With numerous image registration experiments using synthetic and clinical data in both two and three dimensions, we demonstrate that our multiscale registration algorithms enable accurate and efficient registration of medical images that contain levels of noise significantly greater than those at which ordinary registration fails. We also demonstrate that our multiscale techniques are as accurate or more accurate than ordinary techniques for registration of non-noisy medical images.

Download or read book Hybrid Multiscale Landmark and Deformable Image Registration written by and published by . This book was released on 2007 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An image registration technique is presented for the registration of medical images using a hybrid combination of coarse-scale landmark and B-splines deformable registration techniques. The technique is particularly effective for registration problems in which the images to be registered contain large localized deformations. A brief overview of landmark and deformable registration techniques is presented. The hierarchical multiscale image decomposition of E. Tadmor, S. Nezzar, and L. Vese, A multiscale image representation using hierarchical (BV;L2) decompositions, Multiscale Modeling and Simulations, vol. 2, no. 4, pp. 554{579, 2004, is reviewed, and an image registration algorithm is developed based on combining the multiscale decomposition with landmark and deformable techniques. Successful registration of medical images is achieved by first obtaining a hierarchical multiscale decomposition of the images and then using landmark-based registration to register the resulting coarse scales. Corresponding bony structure landmarks are easily identified in the coarse scales, which contain only the large shapes and main features of the image. This registration is then fine tuned by using the resulting transformation as the starting point to deformably register the original images with each other using an iterated multiscale B-splines deformable registration technique. The accuracy and efficiency of the hybrid technique is demonstrated with several image registration case studies in two and three dimensions. Additionally, the hybrid technique is shown to be very robust with respect to the location of landmarks and presence of noise.

Download or read book Translation and Rotation Invariant Multiscale Image Registration written by Jennifer L. Manfra and published by . This book was released on 2002 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most recent research involved registering images in the presence of translations and rotations using one iteration of the redundant discrete wavelet transform. We extend this work by creating a new multiscale transform to register two images with translation or rotation differences, independent of scale differences between the images. Our two-dimensional multiscale transform uses an innovative combination of lowpass filtering and the continuous wavelet transform to mimic the two-dimensional redundant discrete wavelet transform. This allows us to obtain multiple subbands at various scales while maintaining the desirable properties of the redundant discrete wavelet transform. Whereas the discrete wavelet transform produces results only at dyadic scales, our new multiscale transform produces data at all integer scales. This added flexibility improves registration accuracy without greatly increasing computational complexity and permits accurate registration even in the presence of scale differences.

Download or read book Robust and Effective Techniques for Multi modal Image Registration written by Guohua Lv and published by . This book was released on 2015 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image registration is the process of estimating the optimal transformation that aligns different imaging data into spatial correspondences. Multi-modal image registration is to register images which are captured by different types of imaging devices. This thesis aims to develop robust and effective techniques for multi-modal image registration. The challenge lies in the fact that the visual appearance may differ a lot between corresponding parts of multi-modal images. We have been exploring ways by investigating local image features.Two main contributions have been made in this thesis.First, we have improved existing mono-modal and multi-modal image registration techniques by better utilizing gradient information. For a feature-based image registration technique, its effectiveness to a large extent relies on the discrimination power of local descriptors. In the existing techniques, gradient information is utilized in a number of ways for building local descriptors. We have analyzed the limitations of these techniques, and have proposed a technique for better utilizing gradient information. As a result, the discrimination power of local descriptors has been enhanced, leading to a better registration performance.Second, we have developed a new multi-modal image registration technique, which has the following innovations:1. We have proposed a technique to detect the intrinsic structural similarity in multi-modal microscopic images. This is achieved by exploiting the characteristics in intensity relationships between the Red-Green-Blue color channels.2. To increase robustness to content differences, contour-based corners are used, instead of intensity-based keypoints in a state-of-the-art multi-modal image registration technique.3. We have proposed a new local descriptor to better represent corners.4. We have proposed a new way of scale estimation by making use of geometric relationships between corner triplets in two images.The proposed multi-modal image registration technique achieves greater robustness in terms of both content differences and scale differences as compared to the state-of-the-art multi-modal image registration technique.

Download or read book Multi Sensor Imaging and Fusion Methods Evaluations and Applications volume II written by Zhiqin Zhu and published by Frontiers Media SA. This book was released on 2024-07-24 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-sensor image fusion focuses on processing images of the same object or scene acquired by multiple sensors, in which various sensors with multi-level and multi-spatial information are complemented and combined to ultimately yield a consistent interpretation of the observed environment. In recent years, multi-sensor image fusion has become a highly active topic, and various fusion methods have been proposed. Many effective processing methods, including multi-scale transformation, fuzzy inference, and deep learning, have been introduced to design fusion algorithms. Despite the great progress, there are still some noteworthy challenges in the field, such as the lack of unified fusion theories and methods for effective generalized fusion, the lack of fault tolerance and robustness, the lack of benchmarks for performance evaluation, the lack of work on specific applications of multi-sensor image fusion, and so on.
