WebAbstract. An overview of hierarchical data structures for representing images, such as the quadtree and octree, is presented. They are based on the principle of recursive decomposition. The emphasis is on the representation of data used in applications in computer graphics, computer-aided design, robotics, computer vision, and cartography. WebAs the octree structure is discrete and non-differentiable, it is non-trivial to directly employ octree in a learning-based framework. We propose a novel hierarchical network that recursively encodes and decodes both octree structure and geometry features in a differentiable manner. Speciﬁcally, at the
