Modified Parametric Multichannel Wiener Filter \\for Low-latency Enhancement of Speech Mixtures with Unknown Number of Speakers

no code implementations29 Jun 2023 Ning Guo, Tomohiro Nakatani, Shoko Araki, Takehiro Moriya

This paper introduces a novel low-latency online beamforming (BF) algorithm, named Modified Parametric Multichannel Wiener Filter (Mod-PMWF), for enhancing speech mixtures with unknown and varying number of speakers.

Deep sound-field denoiser: optically-measured sound-field denoising using deep neural network

1 code implementation27 Apr 2023 Kenji Ishikawa, Daiki Takeuchi, Noboru Harada, Takehiro Moriya

We compared the method with conventional ones, such as image filters, a spatiotemporal filter, and other DNN architectures, on numerical and experimental data.

A Probabilistic Shaping Approach for Optical Region-of-Interest Signaling

no code implementations2 Sep 2022 Duc-Phuc Nguyen, Yoshifumi Shiraki, Jun Muramatsu, Takehiro Moriya

We propose a probabilistic shaping approach for region-of-interest signaling, where a low-rate signal controls the desired probabilistic ranges of a high-rate data stream using a flexible distribution controller.
