Rephrasing visual questions by specifying the entropy of the answer distribution

Kento Terao, Toru Tamaki, Bisser Raytchev +2

Visual question answering (VQA) is a task of answering a visual question that is a pair of question and image. Some visual questions are ambiguous and some are clear, and it may be…

On-line non-overlapping camera calibration net

Zhao Fangda, Toru Tamaki, Takio Kurita +2

We propose an easy-to-use non-overlapping camera calibration method. First, successive images are fed to a PoseNet-based network to obtain ego-motion of cameras between frames. Nex…

Improved Activity Forecasting for Generating Trajectories

Daisuke Ogawa, Toru Tamaki, Tsubasa Hirakawa +3

An efficient inverse reinforcement learning for generating trajectories is proposed based of 2D and 3D activity forecasting. We modify reward function with norm and propose c…

Semantic segmentation of trajectories with improved agent models for pedestrian behavior analysis

Toru Tamaki, Daisuke Ogawa, Bisser Raytchev +1

In this paper, we propose a method for semantic segmentation of pedestrian trajectories based on pedestrian behavior models, or agents. The agents model the dynamics of pedestrian…

Biomedical Image Segmentation by Retina-like Sequential Attention Mechanism Using Only A Few Training Images

Shohei Hayashi, Bisser Raytchev, Toru Tamaki +1

In this paper we propose a novel deep learning-based algorithm for biomedical image segmentation which uses a sequential attention mechanism able to shift the focus of attention ac…

Semantic segmentation of trajectories with agent models

Daisuke Ogawa, Toru Tamaki, Bisser Raytchev +1

In many cases, such as trajectories clustering and classification, we often divide a trajectory into segments as preprocessing. In this paper, we propose a trajectory semantic segm…
