Heterogeneous Grid Convolution for Adaptive, Efficient, and Controllable Computation

1 code implementation CVPR 2021 Ryuhei Hamaguchi, Yasutaka Furukawa, Masaki Onishi, Ken Sakurada

This paper proposes a novel heterogeneous grid convolution that builds a graph-based image representation by exploiting heterogeneity in the image content, enabling adaptive, efficient, and controllable computations in a convolutional architecture.

Epipolar-Guided Deep Object Matching for Scene Change Detection

no code implementations30 Jul 2020 Kento Doi, Ryuhei Hamaguchi, Shun Iwase, Rio Yokota, Yutaka Matsuo, Ken Sakurada

To cope with the difficulty, we introduce a deep graph matching network that establishes object correspondence between an image pair.

Rare Event Detection using Disentangled Representation Learning

no code implementations CVPR 2019 Ryuhei Hamaguchi, Ken Sakurada, Ryosuke Nakamura

The effectiveness of the proposed approach is verified by the quantitative evaluations on four change detection datasets, and the qualitative analysis shows that the proposed method can acquire the representations that disentangle rare events from trivial ones.
