We present a method that propagates point-wise feature representations across
shapes within a collection for the purpose of 3D shape segmentation. This is
achieved through a cross-shape attention operation that assesses the degree of
interaction between points on different shapes and mediates feature
propagation. For each test shape, our method finds shapes in an input
collection that are suited for executing such cross-shape attention operations.
The resulting point-wise feature representations lead to more consistent 3D
shape segmentation results, as demonstrated …
