Efficient Probabilistic and Geometric Anatomical Mapping Using Particle Mesh Approximation on GPUs

Table 1

Overlap measures comparing the registered segmentation maps against the reference segmentation maps for the parenchyma and cerebellum structure, obtained through without deformation (None), deformable mutual information registration (MI), and our proposed method (P + G).
