Download or read book Optimisation and Performance Evaluation in Image Registration Techniques written by and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, image registration of lung CT scans and brain T1 MRI images were carried out using regular step gradient descent and one to one evolutionary optimisers, and mean squared error and mutual information as similarity metrics. Performance evaluation was done on the two techniques and a comparison done with existing research. Recent research in image registration techniques has demonstrated its worth in a variety of fields from remote sensing to medical imaging. Image registration methods consist of having two input images named as scene and model being made of points. Registration transformation was then done, which relates the two images and similarity metric function that aims to measure a qualitative value of closeness or degree of fitting between the transformed scene image and the model image. Finally, an optimiser which seeks the optimal transformation inside the defined solution search space was performed. The main objective of this research was to apply optimisation methods in image registration techniques in order to provide the user with an estimate as to how accurate the registration actually was. The specific objectives was to determine the transformation model, the similarity metrics in image registration and carry out a careful validation of performance in registration using known basic error classes and methods for measuring registration accuracy and robustness. The main contribution of this research was the significant improvement achieved in image registration when using regular step gradient descent optimisation as shown by the performance evaluation results. The results of structural similarity index values were consistent and very promising, with values close to 1. This was in conformity with theoretical methods and applications. Registration accuracies attained were influenced by the registration techniques chosen.

Download or read book Methods for Evaluating Image Registration written by Joo Hyun Song and published by . This book was released on 2017 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of medical imaging, image registration methods are useful for many applications such as inter- and intra-subject morphological comparisons, creation of population atlases, delivery of precision therapies, etc. A user may want to know which is the most suitable registration algorithm that would work best for the intended application, but the vastness of medical image registration applications makes evaluation and comparison of image registration performance a non-trivial task. In general, evaluating image registration performance is not straightforward because in most image registration applications there is an absence of "Gold Standard" or ground truth correspondence map to compare against. It is therefore the primary goal of this thesis work to provide a means for recommending the most appropriate registration algorithm for a given task. One of the contributions of this thesis is to examine image registration algorithm performance at the component level. Another contribution of this thesis is to catalog the benefits and limitations of many of the most commonly used image registration evaluation approaches. One incremental contribution of this thesis was to demonstrate how existing evaluation methods can be applied in the midpoint coordinate system to evaluate some symmetric image registration algorithms such as the SyN registration algorithm. Finally, a major contribution of this thesis was to develop tools to evaluate and visualize 2D and 3D image registration shape collapse. This thesis demonstrates that many current diffeomorphic image registration algorithms suffer from the collapse problem, provides the first visualizations of the collapse problem in 3D for simple shapes and real human brain MR images, and provides the first experiments that demonstrate how adjusting image registration parameters can mitigate the collapse problem to some extent.

Extracting useful information from 2D/3D data is essential to realizing key technologies underlying our daily lives. Examples include autonomous vehicles and humanoid robots that can recognize and manipulate objects in cluttered environments using stereo vision and laser sensing and medical imaging to localize and diagnose tumors in internal organs using data captured by CT/MRI scans. - Demonstrates how to redesign widely used image registration algorithms so as to best expose the underlying parallelism available in these algorithms - Shows how to pose and implement the parallel versions of the algorithms within the single instruction, multiple data (SIMD) model supported by GPUs - Provides Programming "tricks" that can help readers develop other image processing algorithms, including registration algorithms for the GPU

Download or read book Imaging Vision and Learning Based on Optimization and PDEs written by Xue-Cheng Tai and published by Springer. This book was released on 2018-11-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the peer-reviewed proceedings of the international conference Imaging, Vision and Learning Based on Optimization and PDEs (IVLOPDE), held in Bergen, Norway, in August/September 2016. The contributions cover state-of-the-art research on mathematical techniques for image processing, computer vision and machine learning based on optimization and partial differential equations (PDEs). It has become an established paradigm to formulate problems within image processing and computer vision as PDEs, variational problems or finite dimensional optimization problems. This compact yet expressive framework makes it possible to incorporate a range of desired properties of the solutions and to design algorithms based on well-founded mathematical theory. A growing body of research has also approached more general problems within data analysis and machine learning from the same perspective, and demonstrated the advantages over earlier, more established algorithms. This volume will appeal to all mathematicians and computer scientists interested in novel techniques and analytical results for optimization, variational models and PDEs, together with experimental results on applications ranging from early image formation to high-level image and data analysis.
