POPE: 6-DoF Promptable Pose Estimation of Any Object, in Any Scene, with One Reference

no code implementations25 May 2023 Zhiwen Fan, Panwang Pan, Peihao Wang, Yifan Jiang, Dejia Xu, Hanwen Jiang, Zhangyang Wang

To mitigate this issue, we propose a general paradigm for object pose estimation, called Promptable Object Pose Estimation (POPE).

Outline, Then Details: Syntactically Guided Coarse-To-Fine Code Generation

1 code implementation28 Apr 2023 Wenqing Zheng, S P Sharan, Ajay Kumar Jaiswal, Kevin Wang, Yihan Xi, Dejia Xu, Zhangyang Wang

For a complicated algorithm, its implementation by a human programmer usually starts with outlining a rough control flow followed by iterative enrichments, eventually yielding carefully generated syntactic structures and variables in a hierarchy.

PAIR-Diffusion: Object-Level Image Editing with Structure-and-Appearance Paired Diffusion Models

1 code implementation30 Mar 2023 Vidit Goel, Elia Peruzzo, Yifan Jiang, Dejia Xu, Nicu Sebe, Trevor Darrell, Zhangyang Wang, Humphrey Shi

Nevertheless, most of them lack fine-grained control over the properties of the different objects present in the image, i. e. object-level image editing.

NeuralLift-360: Lifting an In-the-Wild 2D Photo to a 3D Object With 360deg Views

no code implementations CVPR 2023 Dejia Xu, Yifan Jiang, Peihao Wang, Zhiwen Fan, Yi Wang, Zhangyang Wang

In this work, we study the challenging task of lifting a single image to a 3D object and, for the first time, demonstrate the ability to generate a plausible 3D object with 360deg views that corresponds well with the given reference image.

NeuralLift-360: Lifting An In-the-wild 2D Photo to A 3D Object with 360° Views

1 code implementation29 Nov 2022 Dejia Xu, Yifan Jiang, Peihao Wang, Zhiwen Fan, Yi Wang, Zhangyang Wang

In this work, we study the challenging task of lifting a single image to a 3D object and, for the first time, demonstrate the ability to generate a plausible 3D object with 360{\deg} views that correspond well with the given reference image.

Signal Processing for Implicit Neural Representations

no code implementations17 Oct 2022 Dejia Xu, Peihao Wang, Yifan Jiang, Zhiwen Fan, Zhangyang Wang

We answer this question by proposing an implicit neural signal processing network, dubbed INSP-Net, via differential operators on INR.

NeRF-SOS: Any-View Self-supervised Object Segmentation on Complex Scenes

1 code implementation19 Sep 2022 Zhiwen Fan, Peihao Wang, Yifan Jiang, Xinyu Gong, Dejia Xu, Zhangyang Wang

Our framework, called NeRF with Self-supervised Object Segmentation NeRF-SOS, couples object segmentation and neural radiance field to segment objects in any view within a scene.

Unified Implicit Neural Stylization

no code implementations5 Apr 2022 Zhiwen Fan, Yifan Jiang, Peihao Wang, Xinyu Gong, Dejia Xu, Zhangyang Wang

Representing visual signals by implicit representation (e. g., a coordinate based deep network) has prevailed among many vision tasks.

SinNeRF: Training Neural Radiance Fields on Complex Scenes from a Single Image

1 code implementation2 Apr 2022 Dejia Xu, Yifan Jiang, Peihao Wang, Zhiwen Fan, Humphrey Shi, Zhangyang Wang

Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications.
