OrienterNet: Visual Localization in 2D Public Maps with Neural Matching

no code implementations CVPR 2023 Paul-Edouard Sarlin, Daniel DeTone, Tsun-Yi Yang, Armen Avetisyan, Julian Straub, Tomasz Malisiewicz, Samuel Rota Bulo, Richard Newcombe, Peter Kontschieder, Vasileios Balntas

We bridge this gap by introducing OrienterNet, the first deep neural network that can localize an image with sub-meter accuracy using the same 2D semantic maps that humans use.

Nerfels: Renderable Neural Codes for Improved Camera Pose Estimation

no code implementations4 Jun 2022 Gil Avraham, Julian Straub, Tianwei Shen, Tsun-Yi Yang, Hugo Germain, Chris Sweeney, Vasileios Balntas, David Novotny, Daniel DeTone, Richard Newcombe

This paper presents a framework that combines traditional keypoint-based camera pose optimization with an invertible neural rendering mechanism.

NinjaDesc: Content-Concealing Visual Descriptors via Adversarial Learning

no code implementations CVPR 2022 Tony Ng, Hyo Jin Kim, Vincent Lee, Daniel DeTone, Tsun-Yi Yang, Tianwei Shen, Eddy Ilg, Vassileios Balntas, Krystian Mikolajczyk, Chris Sweeney

We let a feature encoding network and image reconstruction network compete with each other, such that the feature encoder tries to impede the image reconstruction with its generated descriptors, while the reconstructor tries to recover the input image from the descriptors.

UR2KiD: Unifying Retrieval, Keypoint Detection, and Keypoint Description without Local Correspondence Supervision

no code implementations20 Jan 2020 Tsun-Yi Yang, Duy-Kien Nguyen, Huub Heijnen, Vassileios Balntas

In this paper, we explore how three related tasks, namely keypoint detection, description, and image retrieval can be jointly tackled using a single unified framework, which is trained without the need of training data with point to point correspondences.

DeepCD: Learning Deep Complementary Descriptors for Patch Representations

1 code implementation ICCV 2017 Tsun-Yi Yang, Jo-Han Hsu, Yen-Yu Lin, Yung-Yu Chuang

This paper presents the DeepCD framework which learns a pair of complementary descriptors jointly for a patch by employing deep learning techniques.

Accumulated Stability Voting: A Robust Descriptor From Descriptors of Multiple Scales

1 code implementation CVPR 2016 Tsun-Yi Yang, Yen-Yu Lin, Yung-Yu Chuang

Experiments on popular benchmarks demonstrate the effectiveness of our descriptors and their superiority to the state-of-the-art descriptors.
