Small Steps and Level Sets: Fitting Neural Surface Models with Point Guidance

no code implementations CVPR 2024 Chamin Hewa Koneputugodage, Yizhak Ben-Shabat, Dylan Campbell, Stephen Gould

We circumvent this problem by introducing guiding points and use them to steer the optimization towards the true shape via small incremental changes for which the loss formulation has a good descent direction.

Octree Guided Unoriented Surface Reconstruction

1 code implementation CVPR 2023 Chamin Hewa Koneputugodage, Yizhak Ben-Shabat, Stephen Gould

We propose a two-step approach, OG-INR, where we (1) construct a discrete octree and label what is inside and outside (2) optimize for a continuous and high-fidelity shape using an INR that is initially guided by the octree's labelling.

Exploiting Problem Structure in Deep Declarative Networks: Two Case Studies

no code implementations24 Feb 2022 Stephen Gould, Dylan Campbell, Itzik Ben-Shabat, Chamin Hewa Koneputugodage, Zhiwei Xu

Deep declarative networks and other recent related works have shown how to differentiate the solution map of a (continuous) parametrized optimization problem, opening up the possibility of embedding mathematical optimization problems into end-to-end learnable models.

DiGS : Divergence guided shape implicit neural representation for unoriented point clouds

1 code implementation21 Jun 2021 Yizhak Ben-Shabat, Chamin Hewa Koneputugodage, Stephen Gould

In this paper, we propose a divergence guided shape representation learning approach that does not require normal vectors as input.
