Abstract: Computing accurate correspondence among 3D shapes is a fundamental and challenging task in the fields of Computer Vision and Graphics. In this talk, I will present our recent works on robust geometric deep learning for both 3D rigid and non-rigid shape matching. Our research highlights the importance of receptive field optimization in neural network designs for handling 3D data with significant geometric variations. I will discuss both spatial and spectral methods incorporating learnable receptive fields, which enable end-to-end informative geometric representation learning and ultimately lead to state-of-the-art matching results.
