Vesselness Estimation through Higher-Order Orientation Tensors
2016 (English)In: International Symposium on Biomedical Imaging (ISBI), IEEE Computer Society, 2016, 1139-1142 p.Conference paper (Refereed)
We recently proposed a method for estimating vesselness based on detection of ring patterns in the local distribution ofthe gradient. This method has a better performance than other state-of-the-art algorithms. However, the original implementation of the method makes use of the spherical harmonics transform locally, which is time consuming. In this paper we propose an equivalent formulation of the method based on higher-order tensors. A linear mapping between the spherical harmonics transform and higher-order orientation tensors is used in order to reduce the complexity of the method. With the new implementation, the analysis of computed tomography angiography data can be performed 2.6 times faster compared with the original implementation.
