Multimedia/Multimodal Signal Analysis and Enhancement Laboratory

The Multimedia/Multimodal Signal Analysis and Enhancement Laboratory (MuSAE Lab) conducts research at the crossroads of biomedical engineering and telecommunications. The MuSAE Lab develops award-winning, biologically inspired signal processing techniques with applications in three areas: multimedia communications, health diagnosis, and human/machine interaction. Data is used to develop human models that will be incorporated into next generation technologies.

The MuSAE Lab boasts:

  • A soundproof data collection room with multimedia displays of various sizes
  • A data collection control room
  • Several multicore analysis PCs and servers (with GPU) for powerful parallel computing analyses

Applications are developed in the following key areas:

Anthropomorphic technology

  • Distributed quality-aware multimedia communications
  • Neural correlates of natural and synthesized speech quality perception
  • Neurophysiological models for “quality-of-experience” prediction
  • Psychoacoustic modelling for the objective assessment of reverberant and dereverberated speech quality
  • Environment-robust speaker identification
  • Multimodal affective state modelling

Health monitoring and diagnoses

  • Quality measurement and enhancement of biomedical signals (e.g., ECG, EEG, EMG)
  • EEG-based diagnosis of Alzheimer’s disease
  • Spectrotemporal signal analysis for cardiopulmonary signals
  • Assistive technology for voiceless communications
  • Objective quantification of handwriting difficulties in school-age children
  • Remote monitoring of dysarthric speech intelligibility

Human/machine interaction

  • Intelligent signal processing for body area networks
  • Hybrid brain-computer interfaces
  • Peripheral autonomic signals for binary control of body/machine interfaces
  • BCI and eye-gaze-based serious gaming
  • Adaptive multimodal HCIs
  • Environment-robust voice-based human/machine interaction

The MuSAE Lab was created in December 2012 with funding from the Canada Foundation for Innovation (CFI) and Ministère de l’Éducation, du Loisir et du Sport.

Through partnerships with the Center for Research on Brain, Language and Music (CRBLM) and the Center for Interdisciplinary Research in Music Media and Technology (CIRMMT), MuSAE Lab teams have access to state-of-the-art recording facilities.

Research at the MuSAE Lab is supported by various provincial and federal research agencies, the INRS Énergie Matériaux Télécommunications Research Centre, manufacturers, and industry partners.
