Identifying Computer-Translated Paragraphs using Coherence Features
Hoang-Quoc Nguyen-Son, Ngoc-Dung T. Tieu, Huy H. Nguyen +2
We have developed a method for extracting the coherence features from a paragraph by matching similar words in its sentences. We conducted an experiment with a parallel German corp…
Audiovisual speaker conversion: jointly and simultaneously transforming facial expression and acoustic characteristics
Fuming Fang, Xin Wang, Junichi Yamagishi +1
An audiovisual speaker conversion method is presented for simultaneously transforming the facial expressions and voice of a source speaker into those of a target speaker. Transform…
Capsule-Forensics: Using Capsule Networks to Detect Forged Images and Videos
Huy H. Nguyen, Junichi Yamagishi, Isao Echizen
Recent advances in media generation techniques have made it easier for attackers to create forged images and videos. State-of-the-art methods enable the real-time creation of a for…
A framework for generalized group testing with inhibitors and its potential application in neuroscience
Thach V. Bui, Minoru Kuribayashi, Mahdi Cheraghchi +1
The main goal of group testing with inhibitors (GTI) is to efficiently identify a small number of defective items and inhibitor items in a large set of items. A test on a subset of…
Transforming acoustic characteristics to deceive playback spoofing countermeasures of speaker verification systems
Fuming Fang, Junichi Yamagishi, Isao Echizen +2
Automatic speaker verification (ASV) systems use a playback detector to filter out playback attacks and ensure verification reliability. Since current playback detection models are…
MesoNet: a Compact Facial Video Forgery Detection Network
Darius Afchar, Vincent Nozick, Junichi Yamagishi +1
This paper presents a method to automatically and efficiently detect face tampering in videos, and particularly focuses on two recent techniques used to generate hyper-realistic fo…
