title: [Paper Introduction] Worldwide Pose Estimation using 3D Point Clouds
abstract: This study address the problem of determining where a photo was taken by estimating a camera pose with respect to a large geo-registered 3D point cloud. The proposed method scales to datasets with hundreds of thousands of images and tens of millions of 3D points through the use of two new techniques: a co-occurrence prior for RANSAC and bidirectional matching of image features with 3D points. The authors evaluate their method on several large data sets, and show state-of-the-art results on landmark recognition as well as the ability to locate cameras to within meters, requiring only seconds per query. language of the presentation: Japanese | ||

title: Lifting 3D Manhattan Lines from a Single Image
abstract: This paper propose a novel and an efficientmethod for reconstructing the 3D arrangement of lines extracted from a single image, using vanishing points, orthogonal structure, and an optimization procedure that considers all plausible connectivity constraints between lines. Line detection identifies a large number of salient lines that intersect or nearly intersect in an image, but relatively a few of these apparent junctions correspond to real intersections in the 3D scene. The research group use linear programming to identify a minimal set of least-violated connectivity constraints that are sufficient to unambiguously reconstruct the 3D lines. The developed algorithm that can work on real images, with a total computation time of 1 second per image. language of the presentation: Japanese | ||

title: Construction of English Text-To-Speech Synthesis for Flexible Control of Speech Intelligibility and Speaker Individuality abstract: A cross-lingual speech synthesis technique, which can generate one language's speech using another language's speech, is expected to apply to the speech-to-speech translation and the dubbing of foreign movies. Because a trade-off relationship between speech intelligibility and speaker individuality is well-known in speech synthesis, it is expected that importance of each factor is different among the applications of cross-lingual speech synthesis. However, the flexible control of those factors is difficult since conventional methods consider only the individuality. Therefore for flexible control, I propose English Text-To-Speech (TTS) synthesis method using both native English speech and English speech by Japanese. I will investigate the features that affect to those factors in TTS that can synthesize speech from text, and I will develop English TTS for flexible control of speech intelligibility and speaker individuality. language of the presentation: Japanese 発表題目: 個人性と明瞭性を制御可能とする英語テキスト音声合成の構築 発表概要: 母語話者の音声を用いて異言語の音声を合成する技術は、音声翻訳や、外国映画の吹き替えへの応用が期待されている。音声合成技術において個人性と明瞭性はトレードオフの関係にあるため、その応用に際し、各性質の重要性が異なることが予想される。しかしながら、従来の技術では明瞭性を強く重視しているため、個人性の高い音声の合成は困難となる。そこで本研究では、個人性と明瞭性を制御可能な合成法として、ネイティブ英語話者の音声と日本語話者の英語音声を用いたテキスト音声合成を提案する。任意のテキストから音声を合成するテキスト音声合成を用いて、個人性及び明瞭性に依存する特徴量を調査し、個人性と明瞭性を制御可能とする音声合成システムの構築を行う。 | ||

title: Development of Low-Cost and Accurate Posturography Using Kinect for In-Home Rehabilitation of Balance Disorders
abstract: Low-cost, compact, and accurate systems for in-home rehabilitation are social needs. We developed a system that measures a user's posture, anterior bending angle, lateral folding angle and center of pressure (COP), by integrating Kinect and Wii Balance Board (WBB). In this study, we first compared the performance of Kinect and an optical motion capture system (MoCap) to validate the accuracy of the developed system. The result showed that the angular data measured by the Kinect and the Mocap had a high correlation coefficient. Next, we investigated the relationship between the angular data and the COP to confirm the necessity of measuring the COP by using WBB. The result suggests that it is not possible to estimate the angles from COP accurately. Overall results suggested that our system has a possibility to provide affordable in-home rehabilitation. language of the presentation: Japanese | ||

title:Development of cell sorting technology using optical tweezers with the particle three-dimensionnal positon estimation and speedup of the sorting
abstract:In medical and pharmaceutical field cell sorting becomes crucial technology for separation of specific specimen among mixed samples. But in conventional sorting methods, there are some fears. For example, it is a limitation of target size and possibility to damage on a sample. In this study, we propose a sorting method to separate objects using optical tweezers. In previous research, it is proposed to separate specimen using optical tweezers from highly mixed sample dispersed in water by flow cell of μTAS technology. However, the method has a problem about a trapping rate and sorting speed. I propose methods to increase a trapping rate by using the particle three-dimensional position estimation. And I propose method to speed up of sorting also. language of the presentation: Japanese | ||

title:Pairing Method for Mobile Devices Based on Multi-sensor Fusion
abstract:We propose a method to make a pair among two nearby mobile devices based on multiple sensor information for instant direct communication. We sometimes use infrared data communication, QR codes, and Bluetooth to exchange email address, photos, and other data with a nearby person by using mobile devices. In addition, like Bump and LINE, applications which make a pair among nearby devices being shaked and start exchanging information among the pair gain a lot of popularity for its easy operation. These applications find the pairing partner based on the location of devices and the timestamp they are shaked. Therefore, only slight error on the positioning by GPS and the detection of shake leads to pairing failure and mispairing with unintended devices.To solve these problems, we propose a pairing method based on multi-sensor fusion scheme. Our method finds the partner based not only on location and timestamp but also on various information around the device such as sound, brightness, signal strength of Bluetooth and WiFi and acceleration and so on. Thus, even if slight error on one or two sensors occurs, our method can recognize the pairing partner accurately based on the other sensor values. language of the presentation: Japanese 発表題目:環境から得られる共通情報を用いたデバイス間のペアリング手法の提案 発表概要:本研究では，同じ場所にいるユーザ同士での情報交換を実現するためのペア作成手法を提案する．携帯電話を用いて情報を交換する既存手法にはQRコードや赤外線，Bluetooth，Bump，LINEなどがある．最近では，BumpやLINEのような，端末を同時に振るという動作をトリガーとして，その位置情報と時刻からユーザ同士をペアリングする手 法が主に利用されている．しかしながら，この手法は，ペアリング時に位置情報と時刻しか比較しないのでペアリングの精度が低いという問題が挙げられる．ペアリングの精度が低下すると，データ交換相手を検出できない検出漏れや，意図しない近隣端末を検出する誤検出が引き起こされる．そこで，本研究では，位置情報と時刻に加え，環境から得られる共通情報を用いることにより，検出漏れと誤検出の両方を低減するペアリングを実 現する．現在，環境から得られる共通情報として，音や照度，BluetoothやWiFiの電波，同一の机においた場合の振動など，いくつかの手法を 検討している段階である． | ||

title: Proposal of a hunger degree estimation system based on activity information
abstract: In recent years, disturbance of the diet has become a problem in many countries including Japan. This problem is caused by the fact that people do eating activities unaware of their hunger state. Thus, realizing the system which estimates strength of the hunger state and recommends the appropriate meal at appropriate time could lead to improvement of the disturbance of the diet. However, it is impossible to obtain the degree of hunger by a commodity device such as a smartphone. Moreover, existing studies use various special devices or invasive procedure, but they still cannot quantify the strength of the hunger.Therefore, in this study, we aim to realize a system which estimates the strength of hunger of the user as the hunger degree, and recommends appropriate meal at appropriate time for the state of the user including the hunger state. To this end, we propose a method for estimating the current hunger degree of the user quantitatively by applying the behavior information which is obtained through the web system or SNS to the hunger degree estimation model. We construct the hunger degree estimation model of two estimation models: (��)a model to estimate a hunger degree from blood glucose level and (��)a model to estimate a hunger degree from blood glucose level. from activity information. To investigate to what extent hunger degree is accurately estimated from blood glucose level, we measured the subjective hunger degree and blood glucose level with the blood glucose measurement sensor. As a result, it was shown that there is a strong positive correlation between the hunger degree and the blood glucose level. language of the presentation: Japanese 発表題目: 過去の行動情報に基づく空腹度推定システムの提案 発表概要: 近年，食生活の乱れが問題視されている．食生活の乱れは，人間が自身の空腹状態を明確に意識せず食事をとる事により誘発される．そこで空腹の強さを推定し，適切な食事・行動を推薦することにより食生活の乱れを改善できると考えられる．しかし，スマートフォンに搭載されているセンサを用いて，空腹の強さを値として直接的に得ることは出来ない．また多くの既存研究は，様々な専用器具や侵襲的（生体を傷つけて行う）な方法を必要とする物であったり，空腹の強さ自体の定量化を行っていない．そこで本研究では，スマートフォンやPC等の一般的な端末を使用して，ユーザの空腹の強さを「空腹度」として非侵襲的に推定し，空腹度に基づいて現在のユーザの状態に最も適切な食事や行動を推薦するシステムを目指す．この目的のため，まず，WebシステムやSNSを通じて取得した過去の行動情報（食事，運動の内容）を空腹度推定モデルに適用し，ユーザの現在の空腹度を定量的に推定する方法を提案する．空腹度推定モデルは血糖値推移をベースに構築し，過去の行動情報から血糖値の推定，血糖値から空腹度の推定の2段階により推定を行う．血糖値から空腹度をどの程度正確に推定できるかを調べるため，血糖値センサによる定期的な血糖値測定，および行動情報の定期的な記録を行った．この測定によって得られたデータと，測定時の実際の空腹感の強さについて相関を調べた結果，血糖値と感覚的な空腹感の推移には強い正の相関がある事がわかった． | ||

title: PPC-based yield improvement by inserting multistage LUTs
abstract: Recently, due to the downscaling of process technology, techniques for yield improvement are demanded. This research aims at improving yield using PPC (Partially-Programmable Circuit) at the logic level. A PPC is made through inserting some Look-Up Tables (LUTs) and redundant wires in conventional logic circuits, which can modify stack-at-faults. However, the places and the number of LUTs to be inserted in PPCs have not been systematically studied yet. Accordingly, this research will study optimization methods to solve these issues, especially by inserting LUTs in a multistage manner. In this presentation, the characteristics and issues of PPCs are first explained, and then our approach and future directions are shown. language of the presentation: Japanese 発表題目:多段ＬＵＴ挿入によるＰＰＣの故障訂正率向上 発表概要: 近年、プロセス微細化技術の発達と共に、更なる歩留まり向上技術が求められている。本研究では、論理設計レベルで回路の歩留まりを向上させるPPC (Partially-Programmable Circuits)に注目する。PPCは組合せ回路中にLUTを挿入し、冗長配線を加えることで縮退故障を回避できる。しかし、LUTの挿入位置や挿入数による故障回避性能の向上については検討されていない。そこで、LUTの挿入位置や数を適切に変更することで、歩留まり率の向上を図る。本発表では、歩留まり向上技術であるPPCの概要と問題点、提案手法と今後の研究の進め方について説明する。 | ||
