PointDiT: Pixel-Space Diffusion for Monocular Geometry Estimation

ICML 2026poster

State-of-the-art single-image 3D reconstruction methods often rely on complex hybrid architectures or necessitate compressing geometry into latent spaces to leverage pre-trained latent diffusion models. In this work, we demonstrate that such architectural overhead is unnecessary. We introduce a mini…

Understanding, Accelerating, and Improving MeanFlow Training

CVPR 2026

MeanFlow promises high-quality generative modeling in few steps, by jointly learning instantaneous and average velocity fields. Yet, the underlying training dynamics remain unclear. We analyze the interaction between the two velocities and find: (i) well-established instantaneous velocity is a prere

CubeDiff: Repurposing Diffusion-Based Image Models for Panorama Generation

ICLR 2025spotlight

We introduce a novel method for generating 360° panoramas from text prompts or images. Our approach leverages recent advances in 3D generation by employing multi-view diffusion models to jointly synthesize the six faces of a cubemap. Unlike previous methods that rely on processing equirectangular pr…

BiasBed - Rigorous Texture Bias Evaluation

CVPR 2023poster

The well-documented presence of texture bias in modern convolutional neural networks has led to a plethora of algorithms that promote an emphasis on shape cues, often to support generalization to new domains. Yet, common datasets, benchmarks and general model selection strategies are missing, and th…

In the Light of Feature Distributions: Moment Matching for Neural Style Transfer

CVPR 2021poster

Style transfer aims to render the content of a given image in the graphical/artistic style of another image. The fundamental concept underlying Neural Style Transfer (NST) is to interpret style as a distribution in the feature space of a Convolutional Neural Network, such that a desired style can be…
