DDM-NET: End-to-end learning of keypoint feature Detection, Description and Matching for 3D localization

1 code implementation8 Dec 2022 Xiangyu Xu, Li Guan, Enrique Dunn, Haoxiang Li, Gang Hua

In this paper, we propose an end-to-end framework that jointly learns keypoint detection, descriptor representation and cross-frame matching for the task of image-based 3D localization.

Efficient 3D space sampling to represent an underlying3D object/scene is essential for 3D vision, robotics, and be-yond.

Beyond Visual Attractiveness: Physically Plausible Single Image HDR Reconstruction for Spherical Panoramas

no code implementations24 Mar 2021 Wei Wei, Li Guan, Yue Liu, Hao Kang, Haoxiang Li, Ying Wu, Gang Hua

By the proposed physical regularization, our method can generate HDRs which are not only visually appealing but also physically plausible.

Pano Popups: Indoor 3D Reconstruction with a Plane-Aware Network

no code implementations1 Jul 2019 Marc Eder, Pierre Moulon, Li Guan

In this work we present a method to train a plane-aware convolutional neural network for dense depth and surface normal estimation as well as plane boundaries from a single indoor $360^\circ$ image.
