arXiv:2406.04309v1 Announce Type: cross Abstract: The common trade-offs of state-of-the-art methods for multi-shape representation (a single model “packing” multiple objects) involve trading modeling accuracy against memory and storage. We show how to encode multiple shapes represented as continuous neural fields with a higher degree of precision than previously possible and with low memory usage. Key to our approach is a recursive hierarchical formulation that exploits object self-similarity, leading to a highly compressed and efficient shape latent space. Thanks to the recursive formulation, our method supports spatial and global-to-local latent feature fusion without needing to initialize and maintain auxiliary data structures, while still allowing for continuous field queries to enable applications such as raytracing. In experiments on a set of diverse datasets, we provide compelling qualitative results and demonstrate state-of-the-art multi-scene reconstruction and compression results with a single network per dataset.
The article “Multi-Shape Representation with Recursive Hierarchical Formulation” addresses the common trade-offs faced by state-of-the-art methods for representing multiple shapes in a single model. These trade-offs typically involve sacrificing modeling accuracy in exchange for memory and storage efficiency. However, the authors propose a novel approach that enables the encoding of multiple shapes as continuous neural fields with higher precision and lower memory usage than previously possible.
The key innovation of their method lies in a recursive hierarchical formulation that takes advantage of object self-similarity. This formulation results in a highly compressed and efficient shape latent space, allowing for spatial and global-to-local latent feature fusion without the need for auxiliary data structures. Moreover, the authors demonstrate that their method supports continuous field queries, enabling applications such as raytracing.
To validate their approach, the authors conduct experiments on diverse datasets. The results showcase compelling qualitative outcomes and demonstrate state-of-the-art multi-scene reconstruction and compression results using only a single network per dataset. Overall, this article presents a promising solution for multi-shape representation that balances modeling accuracy, memory usage, and storage efficiency.
