Gaussian Mixture Selection Using Context-Independent HMM

Akinobu Lee; Tatsuya Kawahara; Kiyohiro Shikano (IEEE, 2001-05)

We address a method to efficiently select Gaussian mixtures for fast acoustic likelihood computation. It makes use of context-independent models for selection and back-off of corresponding triphone models. Specifically, ...
General Architecture for Hardware Implementation of Genetic Algorithm

Tachibana, Tatsuhiro; Murata, Yoshihiro; Shibata, Naoki; Yasumoto, Keiichi; Ito, Minoru (IEEE, 2006)

In this paper, the authors propose a technique to flexibly implement genetic algorithms (GAs) for various problems on FPGAs. For the purpose, the authors propose a common architecture for GA. The proposed architecture ...

Ryo Wakisaka; Hiroshi Saruwatari; Kiyohiro Shikano; Tomoya Takatani (2011)

In this paper, we propose a new method of sound localization preserved noise reduction method for binaural hearing-aid systems. In the previous works, the sound-localization-preserved MMSE STSA estimator with ICA-based ...
A generalized model for visualizing library popularity, adoption, and diffusion within a software ecosystem

Kula, Raula Gaikovina; Roover, Coen De; German, Daniel M.; Ishio, Takashi; Inoue, Katsuro (IEEE, 2018)

The popularity of super repositories such as Maven Central and the CRAN is a testament to software reuse activities in both open-source and commercial projects alike. However, several studies have highlighted the risks and ...
Generation of a Super-Resolved Stereo Video Using Two Synchronized Videos with Different Magnifications

Hayashi, Yusuke; Kawai, Norihiko; Sato, Tomokazu; Okumoto, Miyuki; Yokoya, Naokazu (Springer, 2013)

In this paper, we address the problem of changing the optical zoom magnification of stereo video that uses a stereo camera system with 4K or 8K digital cameras. We proposes a solution for generating a zoomed stereo video ...
Generation of an Omnidirectional Video without Invisible Areas Using Image Inpainting

Kawai, Norihiko; Machikita, Kotaro; Sato, Tomokazu; Yokoya, Naokazu (Springer, 2009)

Omnidirectional cameras usually cannot capture the entire direction of view due to a blind side. Thus, such an invisible part decreases realistic sensation in a telepresence system. In this study, an omnidirectional video ...
Geometric and photometric registration for real-time augmented reality

Kanbara, Masayuki; Yokoya, Naokazu (IEEE, 2002)

This paper proposes an augmented reality system with correct representation of shading and shadow. To realize a seamless augmented reality system, we need to resolve certain problems. The geometric and photometric registration ...
Geometric Registration for Zoomable Camera Using Epipolar Constraint and Pre-calibrated Intrinsic Camera Parameter Change

Takafumi Taketomi,Kazuya Okada,Goshiro Yamamoto,Jun Miyazaki,Hirokazu Kato (IEEE, 2013-10)

In general, video see-through based augmented reality (AR) cannot change the magnification of camera zooming parameter due to the difficulty of dealing with changes in intrinsic camera parameters. To realize the usage of ...
Geometrically-correct projection-based texture mapping onto a cloth

Yuichiro Fujimoto,Jun Miyazaki,Takafumi Taketomi,Hirokazu Kato,Bruce H. Thomas,Goshiro Yamamoto,Ross T. Smith (IEEE, 2014-3)

We demonstrate the geometrically-correct projection-based texture mapping onto a deformable object like a cloth. This system can be used to simulate design that involves change in shape, such as sheets of malleable material. ...
GMM-Based Voice Conversion Applied to Emotional Speech Synthesis

Kawanami, Hiromichi; Iwami, Yohei; Toda, Tomoki; Saruwatari, Hiroshi; Shikano, Kiyohiro (2003-09)

Voice conversion method is applied to synthesizing emotional speech from standard reading ( neutral) speech. Pairs of neutral speech and emotional speech are used for conversion rule training. The conversion adopts GMM ...
Good or Bad Committers? A Case Study of Committers' Cautiousness and the Consequences on the Bug Fixing Process in the Eclipse Project

Jongyindee, Anakorn; Ohira, Masao; Ihara, Akinori; Matsumoto, Ken-ichi (IEEE, 2011)

There are many roles to play in the bug fixing process in open source software development. A developer called ``Committer'', who has a permission to submit a patch into software repository, plays a major role in this ...
GreenSwirl: Combining traffic signal control and route guidance for reducing traffic congestion

Xu, Jiaxing; Sun, Weihua; Shibata, Naoki; Ito, Minoru (IEEE, 2014)

Serious traffic congestion is a major social problem in large cities. Inefficient setting of traffic signal cycles, especially, is one of the main causes of congestion. Green Wave is a method for controlling traffic signals ...
Grid-pattern Indicating Interface for Ambient Assisted Living

Yamamoto, Goshiro; Asghar, Zeeshan; Uranishi, Yuki; Taketomi, Takafumi; Sandor, Christian; Kuroda, Tomohiro; Pulli, Petri; Kato, Hirokazu (ICDVRAT and the University of Reading., 2014)

We propose a grid-pattern indicating interface to provide instructions remotely from remote site to support independent daily life of senior citizens. Our aim is to realize smooth and easy telecommunication between supported ...
Guideline and Tool for Designing an Assembly Task Support System Using Augmented Reality

Tainaka, Keishi; Fujimoto, Yuichiro; Kanbara, Masayuki; Kato, Hirokazu; Moteki, Atsunori; Kuraki, Kensuke; Osamura, Kazuki; Yoshitake, Toshiyuki; Fukuoka, Toshiyuki (IEEE, 2020-11-13)

Augmented reality (AR) systems support complex tasks like assembly by overlaying task-related content onto the real world. In recent years, the effort of designing and developing assembly task support systems in AR decreased ...
Handling categorical variables in effort estimation

Tsunoda, Masateru; Amasaki, Sousuke; Monden, Akito (IEEE, 2012)

Background: Accurate effort estimation is the basis of the software development project management. The linear regression model is one of the widely-used methods for the purpose. A dataset used to build a model often ...
Handling Raw High-Dimensional CAN Bus Data using Long Short-Term Memory Networks for Intrusion Detection in In-Vehicle Networks

Kibrom Desta, Araya; Ohira, Shuji; Arai, Ismail; Fujikawa, Kazutoshi (2020-11-27)

CAN uses no authentication and encryption mechanisms for secure communication. To solve the security issues of the CAN bus, a deep learning-based intrusion detection systems have been proposed. But due to the high dimensional ...
Hands-free Speech Recognition Based on 3-D Viterbi Search Using a Microphone Array
