Correspondences of the Third Kind: Camera Pose Estimation from Object Reflection

no code implementations7 Dec 2023 Kohei Yamashita, Vincent Lepetit, Ko Nishino

In this paper, we introduce correspondences of the third kind we call reflection correspondences and show that they can help estimate camera pose by just looking at objects without relying on the background.

DeepShaRM: Multi-View Shape and Reflectance Map Recovery Under Unknown Lighting

no code implementations26 Oct 2023 Kohei Yamashita, Shohei Nobuhara, Ko Nishino

We introduce a novel deep reflectance map estimation network that recovers the camera-view reflectance maps from the surface normals of the current geometry estimate and the input multi-view images.

nLMVS-Net: Deep Non-Lambertian Multi-View Stereo

no code implementations25 Jul 2022 Kohei Yamashita, Yuto Enyo, Shohei Nobuhara, Ko Nishino

Our key idea is to formulate MVS as an end-to-end learnable network, which we refer to as nLMVS-Net, that seamlessly integrates radiometric cues to leverage surface normals as view-independent surface features for learned cost volume construction and filtering.

3D-GMNet: Single-View 3D Shape Recovery as A Gaussian Mixture

no code implementations10 Dec 2019 Kohei Yamashita, Shohei Nobuhara, Ko Nishino

In this paper, we introduce 3D-GMNet, a deep neural network for 3D object shape reconstruction from a single image.
