Travel destination recommendation is useful to support travel.Considering the recommendation of regions within the destination area to visit, it could be difficult for the users to explicitly indicate their preference.Therefore, we considered that it would be more intuitive to recommend regions in the destination area that are similar to a region already well-known to the user.Thus, in this paper, we propose a method for the detection of similar geo-regions based on Visual Concepts in social photos.We report experimental results and analyses by applying the proposed method to the YFCC100M dataset.

本講演では，医用画像処理に軸足を置いた研究から私自身経験の無いITS研究分野に挑戦したこれまでの経験を紹介するとともに，そこで感じた研究分野を変えることの難しさ，新しいことへの挑戦の楽しさ，人との繋がりの大切さ，などについてまとめる．私自身は，名古屋大学工学部の4年生として鳥脇研究室の門をくぐり，博士号取得まで一貫して医用画像処理，特に気管支内視鏡ナビゲーションシステムの開発と関連するセグメンテーション技術の開発に取り組んできた．その後，縁あってコンピュータービジョン・パターン認識などの研究に軸足を移し，現在ではITSに関連する研究にも取り組んでいる．その間，研究分野を変えることの難しさや，新しいことに挑戦する楽しさを再認識することができた．特に，新しい人との繋がりは自身を大きく成長させてくれたと考えている．このような私自身のこれまでの経験が，今後新しい研究分野に挑戦する研究者の皆様の助けになれば幸いである．

Headgear Recognition by Decomposing Human Images in the Thermal Infrared Spectrum International conference

Surveillance systems play a critical role in security and surveillance. A surveillance system with cameras that work in the visible spectrum is sufficient for most cases. However, problems may arise during the night, or in areas with less than ideal illumination conditions. Cameras with thermal infrared technology can be a better option in these situations since they do not rely on illumination to observe the environment. Furthermore, in our daily lives, it is common for humans to wear headgears such as glasses, masks, and hats. In surveillance, such headgears can be a hindrance to the identification of a person, and hence pose a certain degree of risk. This is not ideal in areas where the identity of a person is important, for example, in a bank. Therefore, in this paper we propose a headgear recognition method using an innovative decomposition approach on thermal infrared images. The decomposition method is based on Robust Principal Component Analysis, a modification of the popular Principal Component Analysis. The proposed method performs decomposition on a human image and isolates headgears in the image for recognition purposes. Experiments were conducted to evaluate the capability of the proposed method. The results show a positive outcome when compared with other methods.

Trajectory Ensemble: Multiple Persons Consensus Tracking across Non-overlapping Multiple Cameras over Randomly Dropped Camera Networks International conference

Yasutomo Kawanishi, Daisuke Deguchi, Ichiro Ide, Hiroshi Murase

1st Workshop on Target Re-Identification and Multi-Target Multi-Camera Tracking 2017.7.21

Event date： 2017

Language：English Presentation type：Poster presentation

Venue：Hawaii Convention Center

Multiple person tracking over a camera network is usually performed by matching person images between adjacent cameras. It easily fails by a temporal appearance change of the persons caused by environmental illumination and observation orientation of a camera. To solve this problem, matching person images across not only adjacent cameras but also cameras multiple hops away in the camera network is effective, but such relaxation of spatiotemporal cues also cause tracking failure due to the increase of matching candidates. To avoid the failure, we introduce Random Camera Drop" to generate different camera networks which relax the spatio-temporal cues partially and randomly. We then, integrate tracking results over the networks to a consensus tracking result by a novel concept "Trajectory Ensemble", an extension of unsupervised ensemble learning for the multiple person tracking over a camera network problem. We evaluated the framework on several virtual datasets generated from a public dataset, "Shinpuhkan 2014 dataset" and confirmed that the proposed method achieves the highest tracking results among several comparative methods."

Monocular Localization within Sparse Voxel Maps International conference

2017 IEEE Intelligent Vehicles Symposium (IV2017) 2017.6.12

Venue：Redondo Beach, California, USA

We introduce a method that uses a single camera to localize a vehicle within a pre-constructed map consisting of a voxel occupancy grid and road-line marker positions. Sophisticated mapping hardware is capable of creating high accuracy 3D maps of road environments, but localizing a vehicle within such maps is one of the challenges at the forefront of automated driving. A solution which is robust to dynamic environments, while using only inexpensive sensors, is a difficult problem. In addition, maps that enable precise localization consume a lot of data which is impractical for the expansive environments encountered in real-world road networks. We show how using the area of edge regions shared between rendered views of a compact voxel map and in-vehicle camera images can be coupled with non-linear optimization methods to determine the camera position and pose.
