Joint Recovery of Dense Correspondence and Cosegmentation in Two Images

Tatsunori Taniai, Sudipta N. Sinha, Yoichi Sato
2016 IEEE Conference on Computer Vision and…
2016

We propose a new technique to jointly recover cosegmentation and dense per-pixel correspondence in two images. Our method parameterizes the correspondence field using piecewise similarity… (More)

Graph Cut Based Continuous Stereo Matching Using Locally Shared Labels

Tatsunori Taniai, Yasuyuki Matsushita, Takeshi Naemura
2014 IEEE Conference on Computer Vision and…
2014

We present an accurate and efficient stereo matching method using locally shared labels, a new labeling scheme that enables spatial propagation in MRF inference using graph cuts. They give each pixel… (More)

Continuous 3D Label Stereo Matching Using Local Expansion Moves

Tatsunori Taniai, Yasuyuki Matsushita, Yoichi Sato, Takeshi Naemura
IEEE Transactions on Pattern Analysis and Machine…
2018

We present an accurate stereo matching method using <italic>local expansion moves</italic> based on graph cuts. This new move-making scheme is used to efficiently infer per-pixel 3D plane labels on a… (More)

Fast Multi-frame Stereo Scene Flow with Motion Segmentation

Tatsunori Taniai, Sudipta N. Sinha, Yoichi Sato
2017 IEEE Conference on Computer Vision and…
2017

We propose a new multi-frame method for efficiently computing scene flow (dense depth and optical flow) and camera ego-motion for a dynamic scene observed from a moving stereo camera rig. Our… (More)

Neural Inverse Rendering for General Reflectance Photometric Stereo

In Figures A1–A10, we show surface normal estimates and their angular error maps for all ten scenes from the DiLiGenT dataset, comparing our method with three methods by Santo et al. (2017), Shi et… (More)

Image Segmentation using Dual Distribution Matching

Tatsunori Taniai, Viet Quoc Pham, Keita Takahashi, Takeshi Naemura
BMVC
2012

We propose an image segmentation method that divides an image into foreground and background regions when the approximate color distributions for these regions are given. Our approach was inspired by… (More)

Neural Photometric Stereo Reconstruction for General Reflectance Surfaces

We present a novel convolutional neural network architecture for photometric stereo (Woodham, 1980), a problem of recovering 3D object surface normals from multiple images observed under varying… (More)

Superdifferential cuts for binary energies

Tatsunori Taniai, Yasuyuki Matsushita, Takeshi Naemura
2015 IEEE Conference on Computer Vision and…
2015

We propose an efficient and general purpose energy optimization method for binary variable energies used in various low-level vision tasks. Our method can be used for broad classes of higher-order… (More)

Semi-global Stereo Matching with Surface Orientation Priors

Daniel Scharstein, Tatsunori Taniai, Sudipta N. Sinha
2017 International Conference on 3D Vision (3DV)
2017

Semi-Global Matching (SGM) is a widely-used efficient stereo matching technique. It works well for textured scenes, but fails on untextured slanted surfaces due to its fronto-parallel smoothness… (More)

A soft environmental control effect of apatite doped with mineral traces in the fowl droppings.

Mayumi Minamisawa, Tatsunori Taniai, Shinobu Yoshida
Poultry science
2017

Fowl-dropping apatite (Ca10-z[PO4]6-z[OH]2-z) synthesized from carbonized, incinerated fowl droppings contains PO4 and OH groups that are partially substituted by CO32- ions. It shows stronger ion… (More)
