IM-3D: Iterative Multiview Diffusion and Reconstruction for High-Quality 3D Generation

Luke Melas-Kyriazi, Iro Laina, Christian Rupprecht +4

Most text-to-3D generators build upon off-the-shelf text-to-image models trained on billions of images. They use variants of Score Distillation Sampling (SDS), which is slow, somew…

GES: Generalized Exponential Splatting for Efficient Radiance Field Rendering

Abdullah Hamdi, Luke Melas-Kyriazi, Jinjie Mai +5

Advancements in 3D Gaussian Splatting have significantly accelerated 3D reconstruction and generation. However, it may require a large number of Gaussians, which creates a substant…

Understanding Self-Supervised Features for Learning Unsupervised Instance Segmentation

Paul Engstler, Luke Melas-Kyriazi, Christian Rupprecht +1

Self-supervised learning (SSL) can be used to solve complex visual tasks without human labels. Self-supervised representations encode useful semantic information about images, and…

: Projection-Conditioned Point Cloud Diffusion for Single-Image 3D Reconstruction

Luke Melas-Kyriazi, Christian Rupprecht, Andrea Vedaldi

Reconstructing the 3D shape of an object from a single RGB image is a long-standing and highly challenging problem in computer vision. In this paper, we propose a novel method for…

RealFusion: 360° Reconstruction of Any Object from a Single Image

Luke Melas-Kyriazi, Christian Rupprecht, Iro Laina +1

We consider the problem of reconstructing a full 360° photographic model of an object from a single image of it. We do so by fitting a neural radiance field to the image, but find…

Deep Spectral Methods: A Surprisingly Strong Baseline for Unsupervised Semantic Segmentation and Localization

Luke Melas-Kyriazi, Christian Rupprecht, Iro Laina +1

Unsupervised localization and segmentation are long-standing computer vision challenges that involve decomposing an image into semantically-meaningful segments without any labeled…
