This paper proposes a background estimation method from a single omnidirectional image sequence for removing undesired regions such as moving objects, specular regions, and uncaptured regions caused by the camera's blind ...

An important character of on-line learning is its potential to adapt to changing environments by properly adjusting meta-parameters that control the balance between plasticity and stability of the learning model. In our ...

Aiming at fast establishment of a wireless network around a multi-level building in a disaster area, we propose an efficient method to determine the locations of network nodes in the air. Nodes are attached to balloons ...

Bandwidth extension is a useful technique for reconstructing wideband speech from only narrowband speech. As a typical conventional method, a bandwidth extension algorithm based on minimum mean square eηor (MMSE) with a ...

This paper describes a new small-scale interface for a barge-in free spoken dialogue system combining a multichannel sound field control and a microphone array, in which the response sound from the system can be canceled ...

For hands-free spoken dialogue system, we propose an interface to eliminate known noise outputted by the dialogue system and unknown noise sufficiently by giving known source of the loudspeaker output. Moreover, elimination ...

A binaural hearing-aid system based on two-stage blind sound source separation (BSS) method is now being studied by some of the authors. This system consists of two techniques; a single-input multiple-output (SIMO)-model-based ...
