SPHARM-Net: Spherical Harmonics-based Convolutional Neural Network

We propose an effective spherical deformation-based sulcal labeling method that automatically enlarges sulcal ROIs while contracting unlabeled regions. By designing an invertible, learnable isotropic deformation field with end-to-end SO(3)-equivariance, the proposed method enhances expressive power and generalization capability under data scarcity.
