ConsistNet: Enforcing 3D Consistency for Multi-view Images Diffusion

1 code implementation16 Oct 2023 Jiayu Yang, Ziang Cheng, Yunfei Duan, Pan Ji, Hongdong Li

Given a single image of a 3D object, this paper proposes a novel method (named ConsistNet) that is able to generate multiple images of the same object, as if seen they are captured from different viewpoints, while the 3D (multi-view) consistencies among those multiple generated images are effectively exploited.

Stereo Matching in Time: 100+ FPS Video Stereo Matching for Extended Reality

no code implementations8 Sep 2023 Ziang Cheng, Jiayu Yang, Hongdong Li

One of the major difficulties is the lack of high-quality indoor video stereo training datasets captured by head-mounted VR/AR glasses.

Multi-view 3D Reconstruction of a Texture-less Smooth Surface of Unknown Generic Reflectance

1 code implementation CVPR 2021 Ziang Cheng, Hongdong Li, Yuta Asano, Yinqiang Zheng, Imari Sato

Recovering the 3D geometry of a purely texture-less object with generally unknown surface reflectance (e. g. non-Lambertian) is regarded as a challenging task in multi-view reconstruction.

One Ring to Rule Them All: a simple solution to multi-view 3D-Reconstruction of shapes with unknown BRDF via a small Recurrent ResNet

no code implementations11 Apr 2021 Ziang Cheng, Hongdong Li, Richard Hartley, Yinqiang Zheng, Imari Sato

This paper proposes a simple method which solves an open problem of multi-view 3D-Reconstruction for objects with unknown and generic surface materials, imaged by a freely moving camera and a freely moving point light source.

Semantic Single-Image Dehazing

no code implementations16 Apr 2018 Ziang Cheng, ShaoDi You, Viorela Ila, Hongdong Li

In experiments, we validate our ap- proach upon synthetic and real hazy images, where our method showed superior performance over state-of-the-art approaches, suggesting semantic information facilitates the haze removal task.
