Graph Representation for Order-Aware Visual Transformation

no code implementations CVPR 2023 Yue Qiu, Yanjun Sun, Fumiya Matsuzawa, Kenji Iwata, Hirokatsu Kataoka

This paper proposes a new visual reasoning formulation that aims at discovering changes between image pairs and their temporal orders.

Describing and Localizing Multiple Changes with Transformers

2 code implementations ICCV 2021 Yue Qiu, Shintaro Yamamoto, Kodai Nakashima, Ryota Suzuki, Kenji Iwata, Hirokatsu Kataoka, Yutaka Satoh

Change captioning tasks aim to detect changes in image pairs observed before and after a scene change and generate a natural language description of the changes.

Can Vision Transformers Learn without Natural Images?

1 code implementation24 Mar 2021 Kodai Nakashima, Hirokatsu Kataoka, Asato Matsumoto, Kenji Iwata, Nakamasa Inoue

Moreover, although the ViT pre-trained without natural images produces some different visualizations from ImageNet pre-trained ViT, it can interpret natural image datasets to a large extent.

Dominant Codewords Selection with Topic Model for Action Recognition

no code implementations1 May 2016 Hirokatsu Kataoka, Masaki Hayashi, Kenji Iwata, Yutaka Satoh, Yoshimitsu Aoki, Slobodan Ilic

Latent Dirichlet allocation (LDA) is used to develop approximations of human motion primitives; these are mid-level representations, and they adaptively integrate dominant vectors when classifying human activities.

Feature Evaluation of Deep Convolutional Neural Networks for Object Recognition and Detection

no code implementations25 Sep 2015 Hirokatsu Kataoka, Kenji Iwata, Yutaka Satoh

In this paper, we evaluate convolutional neural network (CNN) features using the AlexNet architecture and very deep convolutional network (VGGNet) architecture.
