WebContributed to the spherical demons matlab software of B.T. Thomas Yeo. Spherical Demons is an algorithm that registers spherical images. Registration between a 160k vertices subject mesh and an atlas takes less than 5 mins on a Xeon 3.2GHz single processor machine, which is more than 10 times faster than the popular, freely-available … WebOct 1, 2024 · Although Spherical Demons and the proposed method achieved comparable computation time for individual subject registration, FreeSurfer, Spherical Demons, and the proposed method took about 90 hours, 21 hours, and 7 hours for the entire subjects, respectively, after all rounds of co-registration. Fig. 7 shows the average hCurv features. It …

(PDF) Spherical Demons: Fast Surface Registration
WebJan 15, 2011 · ITK has recently added the ability to register surfaces in the spherical domain based on the quad edge mesh data structure. This includes both rotational and deformable registrations of two meshes [1, 2]. The deformable registration of two meshes was implemented using the spherical demons registration as proposed by Yeo et al. [3]. Based … WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. We present the fast Spherical Demons algorithm for registering two spherical images. By exploiting spherical vector spline interpolation theory, we show that a large class of regularizers for the modified demons objective function can be efficiently implemented on … WebWe present a multi-cohort shape heritability study, extending the fast spherical demons registration to subcortical shapes via medial modeling. A multi-channel demons registration based on vector spherical harmonics is applied to medial and curvature features, while controlling for metric distortion. bycab-130-al-bk
