Surface registration between cortical surfaces is crucial in medical imaging for performing systematic comparisons between brains. Landmark-matching registration that matches anatomical features, called the sulcal landmarks, is often required to obtain a meaningful 1-1 correspondence between brain surfaces. This is commonly done by parameterizing the surface onto a simple parameter domain, such as the unit sphere, in which the sulcal landmarks are consistently aligned. Landmark-matching surface…

This work presents an efficient method to compute the registration between surfaces with consistent graph constraints based on Tutte graph embedding, which solves sparse linear systems and is computationally efficient and robust.
Large Deformation Multiresolution Diffeomorphic Metric Mapping for Multiresolution Cortical Surfaces: A Coarse-to-Fine Approach
A fast coarse-to-fine algorithm for surface registration is proposed by adapting the large diffeomorphic deformation metric mapping (LDDMM) framework for surface mapping and improvements in speed and accuracy are shown via a multiresolution analysis of surface meshes and the construction ofMultiresolution diffeomorph transformations.
Shape analysis via inconsistent surface registration
This work develops a framework for shape analysis using inconsistent surface mapping using quasi-conformal distortion and differences in mean and Gaussian curvatures, thereby providing a natural way for shape classification and shed light on the interplay between function and shape in nature.
Structural Surface Mapping for Shape Analysis
This dissertation explores structural mappings for shape analysis of surfaces using the feature graphs as constraints by proposing structural brain mapping which maps the brain cortical surface onto a planar convex domain and proposing a novel brain registration technique based on an intrinsic atlas-constrained harmonic map.
Intrinsic Patch-Based Cortical Anatomical Parcellation Using Graph Convolutional Neural Network on Surface Manifold
The method aims to learn the highly nonlinear mapping between cortical attribute patterns (on local intrinsic surface patches) and parcellation labels, which achieves comparable accuracy to the methods using spherical mapping, and works well on cortical surfaces violating the spherical topology.
Modeling the Space of Point Landmark Constrained Diffeomorphisms
A novel model of the space of point landmark constrained diffeomorphisms based on Teichmuller theory, where the Beltrami coefficients are the solutions to a linear equation group, is proposed, which proves the efficiency and efficacy of the proposed method.


Surface-Constrained Volumetric Brain Registration Using Harmonic Mappings
This work describes a method for volumetric registration that also produces an accurate one-to-one point correspondence between cortical surfaces by first parameterizing and aligning the cortical surfaces using sulcal landmarks and then using a constrained harmonic mapping to extend this surface correspondence to the entire cortical volume.
Optimized Conformal Surface Registration with Shape-based Landmark Matching
This work generates optimized conformal parameterizations which match landmark curves exactly with shape-based correspondences between them and proposes a variational method to minimize a compound energy functional that measures the harmonic energy of the parameterization maps and the shape dissimilarity between mapped points on the landmark curves.

The algorithm is applied to study constrained human brain surface registration problem and demonstrates that, by changing the Riemannian metric, the registrations are always diffeomorphic, and achieve relative high performance when evaluated with some popular cortical surface registration evaluation standards.
Diffeomorphic Sulcal Shape Analysis on the Cortex
A diffeomorphic approach for constructing intrinsic shape atlases of sulci on the human cortex by computing geodesics in the quotient space of shapes modulo scales, translations, rigid rotations, and reparameterizations is presented.
Optimization of Brain Conformal Mapping with Landmarks
A new method is proposed, based on a new energy functional, to optimize the conformal parameterization of cortical surfaces by using landmarks, showing that the landmark mismatch energy can be greatly reduced while effectively preserving conformality.
Diffeomorphic Brain Registration Under Exhaustive Sulcal Constraints
A global, geometric approach that performs the alignment of the exhaustive sulcal imprints (cortical folding patterns) across individuals and how the optimized alignment of cortical folds across subjects improves sensitivity in the detection of functional activations in a group-level analysis of neuroimaging data is illustrated.
Brain Surface Conformal Parameterization Using Riemann Surface Structure
A parameterization method based on Riemann surface structure is introduced, which uses a special curvilinear net structure (conformal net) to partition the surface into a set of patches that can each be conformally mapped to a parallelogram.
