A Simple Approach to Intrinsic Correspondence Learning on Unstructured 3D Meshes

no code implementations18 Sep 2018 Isaak Lim, Alexander Dielen, Marcel Campen, Leif Kobbelt

The question of representation of 3D geometry is of vital importance when it comes to leveraging the recent advances in the field of machine learning for geometry processing tasks.

A Convolutional Decoder for Point Clouds using Adaptive Instance Normalization

no code implementations27 Jun 2019 Isaak Lim, Moritz Ibing, Leif Kobbelt

In addition, we show that careful sampling is important both for the input geometry and in our point cloud generation process to improve results.

3D Shape Generation with Grid-based Implicit Functions

no code implementations CVPR 2021 Moritz Ibing, Isaak Lim, Leif Kobbelt

To remedy these issues, we propose to train the GAN on grids (i. e. each cell covers a part of a shape).

Localized Latent Updates for Fine-Tuning Vision-Language Models

no code implementations13 Dec 2022 Moritz Ibing, Isaak Lim, Leif Kobbelt

Although massive pre-trained vision-language models like CLIP show impressive generalization capabilities for many tasks, still it often remains necessary to fine-tune them for improved performance on specific datasets.

Adaptive Voronoi NeRFs

no code implementations28 Mar 2023 Tim Elsner, Victor Czech, Julia Berger, Zain Selman, Isaak Lim, Leif Kobbelt

Neural Radiance Fields (NeRFs) learn to represent a 3D scene from just a set of registered images.

Partial Symmetry Detection for 3D Geometry using Contrastive Learning with Geodesic Point Cloud Patches

no code implementations13 Dec 2023 Gregor Kobsik, Isaak Lim, Leif Kobbelt

To our knowledge, we are the first to propose a self-supervised data-driven method for partial extrinsic symmetry detection.
