Optimal Transport with Cyclic Symmetry

no code implementations22 Nov 2023 Shoichiro Takeda, Yasunori Akagi, Naoki Marumo, Kenta Niwa

On the basis of this reduction, our algorithms solve the small optimization problem instead of the original OT.

Bilateral Video Magnification Filter

no code implementations CVPR 2022 Shoichiro Takeda, Kenta Niwa, Mariko Isogawa, Shinya Shimizu, Kazuki Okami, Yushi Aono

Eulerian video magnification (EVM) has progressed to magnify subtle motions with a target frequency even under the presence of large motions of objects.

Image Enhanced Rotation Prediction for Self-Supervised Learning

no code implementations25 Dec 2019 Shin'ya Yamaguchi, Sekitoshi Kanai, Tetsuya Shioda, Shoichiro Takeda

The rotation prediction (Rotation) is a simple pretext-task for self-supervised learning (SSL), where models learn useful representations for target vision tasks by solving pretext-tasks.

Video Magnification in the Wild Using Fractional Anisotropy in Temporal Distribution

no code implementations CVPR 2019 Shoichiro Takeda, Yasunori Akagi, Kazuki Okami, Megumi Isogai, Hideaki Kimata

On the basis of our observation that temporal distribution of meaningful subtle changes more clearly indicates anisotropic diffusion than that of non-meaningful ones, we used FA to design a fractional anisotropic filter that passes only meaningful subtle changes.
