Logging is an important feature for a software system to record its run-time information. Although detailed logs are helpful to identify the cause of a failure in a program execution, constantly recording detailed logs of ...

We propose a two-stage blind separation and deconvolution (BSD) algorithm for a convolutive mixture of temporally correlated signals, in which a new single-input multiple-output (SIMO)-model-based ICA (SIMO-ICA) and blind ...

In recent years, some bus companies have raised revenue by reviewing the route plan using the number of passengers. The company has a system that can automatically counts the number of passengers on an ongoing basis. But ...

Our reasearch goal is to construct a Japanese TTS (Text-to-Speech) system that can output various kinds of prosody. Since such synthetic speech is useful for a practical use, many TTS systems have implemented global prosodic ...

A hands-free system with conventional independent component analysis (ICA) should update the separation filter constantly to follow the hourly environment change. However, when the separation-filter is updated in the period ...

Recently, various personal navigation systems are available on the market. In this paper, we propose a new scheduling function to compose sightseeing tours across multiple days. Scheduling for multiple days is challenging ...

This paper describes photometric registration for augmented reality (AR) using a high-dynamic-range (HDR) image. In photorealistic AR, estimating the lighting environment of virtual objects is difficult because of low ...

The pitch recognition of musical sounds is one of the indispensable technologies for realizing an automatic copy-down-a-tune system. Recently various researches for the pitch recognition have been studied. In many pitch ...

We present a novel method for estimating 3-D positions of near light sources by using highlights on the outside and inside of a single clear hollow sphere. Conventionally, the positions of near light sources have been ...

At-speed scan testing may suffer from severe yield loss due to the launch safety problem, where test responses are invalidated by excessive launch switching activity (LSA) caused by test stimulus launching in the at-speed ...
