Deep Depth from Focal Stack with Defocus Model for Camera-Setting Invariance

no code implementations26 Feb 2022 Yuki Fujimura, Masaaki Iiyama, Takuya Funatomi, Yasuhiro Mukaigawa

Our method takes a plane sweep volume as input for the constraint between scene depth, defocus images, and camera settings, and this intermediate representation enables depth estimation with different camera settings at training and test times.

Dehazing Cost Volume for Deep Multi-view Stereo in Scattering Media with Airlight and Scattering Coefficient Estimation

1 code implementation18 Nov 2020 Yuki Fujimura, Motoharu Sonogashira, Masaaki Iiyama

We also propose a method of estimating scattering parameters, such as airlight, and a scattering coefficient, which are required for our dehazing cost volume.

Partially-Shared Variational Auto-encoders for Unsupervised Domain Adaptation with Target Shift

1 code implementation ECCV 2020 Ryuhei Takahashi, Atsushi Hashimoto, Motoharu Sonogashira, Masaaki Iiyama

In practice, this is an important problem in UDA; as we do not know labels in target domain datasets, we do not know whether or not its distribution is identical to that in the source domain dataset.

Defogging Kinect: Simultaneous Estimation of Object Region and Depth in Foggy Scenes

no code implementations1 Apr 2019 Yuki Fujimura, Motoharu Sonogashira, Masaaki Iiyama

The scattering component is saturated, so it does not depend on the scene depth, and received signals bouncing off distant points are negligible due to light attenuation in the participating media, so the observation of such a point contains only a scattering component.

Outlier Cluster Formation in Spectral Clustering

no code implementations3 Mar 2017 Takuro Ina, Atsushi Hashimoto, Masaaki Iiyama, Hidekazu Kasahara, Mikihiko Mori, Michihiko Minoh

The highlights of this paper are the following two mathematical observations: first, spectral clustering's intrinsic property of an outlier cluster formation, and second, the singularity of an outlier cluster with a valid cluster number.
