4D Reconstruction from Sparse Dynamic Cameras

Kazuki Ozeki, Shun Kenney, Yuto Shibata +6

Although dynamic 3D (i.e., 4D) reconstruction from a monocular dynamic camera has recently advanced, it remains fundamentally limited by depth ambiguity. In this paper, we focus on…

MMAudioReverbs: Video-Guided Acoustic Modeling for Dereverberation and Room Impulse Response Estimation

Akira Takahashi, Ryosuke Sawata, Shusuke Takahashi +1

Although recent video-to-audio (V2A) models excelled at synthesizing semantically plausible sounds from visual inputs, they do not explicitly model room-acoustic effects such as re…

HumanGif: Single-View Human Diffusion with Generative Prior

Shoukang Hu, Takuya Narihira, Kazumi Fukuda +3

Previous 3D human creation methods have made significant progress in synthesizing view-consistent and temporally aligned results from sparse-view images or monocular videos. Howeve…

The Whole Is Greater than the Sum of Its Parts: Improving Music Source Separation by Bridging Network

Ryosuke Sawata, Naoya Takahashi, Stefan Uhlich +2

This paper presents the crossing scheme (X-scheme) for improving the performance of deep neural network (DNN)-based music source separation (MSS) with almost no increasing calculat…

Diffusion-based Signal Refiner for Speech Enhancement and Separation

Masato Hirano, Ryosuke Sawata, Naoki Murata +2

Although recent speech processing technologies have achieved significant improvements in objective metrics, there still remains a gap in human perceptual quality. This paper propos…

DiffRoll: Diffusion-based Generative Music Transcription with Unsupervised Pretraining Capability

Kin Wai Cheuk, Ryosuke Sawata, Toshimitsu Uesaka +5

In this paper we propose a novel generative approach, DiffRoll, to tackle automatic music transcription (AMT). Instead of treating AMT as a discriminative task in which the model i…

Diffiner: A Versatile Diffusion-based Generative Refiner for Speech Enhancement

Ryosuke Sawata, Naoki Murata, Yuhta Takida +4

Although deep neural network (DNN)-based speech enhancement (SE) methods outperform the previous non-DNN-based ones, they often degrade the perceptual quality of generated outputs.…

Improving Character Error Rate Is Not Equal to Having Clean Speech: Speech Enhancement for ASR Systems with Black-box Acoustic Models

Ryosuke Sawata, Yosuke Kashiwagi, Shusuke Takahashi

A deep neural network (DNN)-based speech enhancement (SE) aiming to maximize the performance of an automatic speech recognition (ASR) system is proposed in this paper. In order to…

Manifold-Aware Deep Clustering: Maximizing Angles between Embedding Vectors Based on Regular Simplex

Keitaro Tanaka, Ryosuke Sawata, Shusuke Takahashi

This paper presents a new deep clustering (DC) method called manifold-aware DC (M-DC) that can enhance hyperspace utilization more effectively than the original DC. The original DC…

All for One and One for All: Improving Music Separation by Bridging Networks

Ryosuke Sawata, Stefan Uhlich, Shusuke Takahashi +1

This paper proposes several improvements for music separation with deep neural networks (DNNs), namely a multi-domain loss (MDL) and two combination schemes. First, by using MDL we…
