    Signal and data processing for vital sign data

    The outbreak of infectious diseases is threatening global health. Especially, in the South-East Asia region have been at serious risk. At mass gathering places, such as, airport quarantine facilities, public health centers, and hospital out patients units, rapid and highly reliable screening methods of infection are urgently needed during the epidemic season for preventing the spread of infection.

    To meet this need, the University of Electronics and Communications (UEC) of Japan and partner institutions of UEC, National Hospital of Tropical Diseases, Hanoi (NHTD), and Tokyo Metropolitan University (TMU), have been developing multiple vital-signs based infection screening systems. This screening system monitors not only body temperature but also heart and respiration rates. However, accuracy of the data processing is not sufficient for the screening of the diseases for short time. This project is carried out in cooperation between the VNU University of Engineering and Technology (VNU-UET), Vietnam National University, Hanoi (VNU) and UEC.

    The goal of this project is to develop signal and data processing method of the data from the multiple vital-sign-based infections screening system to improve the screening rate. To develop hazard map generating system, which predicts the area of infection diseases is the next target. The data will be provided by UEC to VNU-UET. The data processing methods include not only analog and digital signal processing methods but also the data processing by AI (Artificial Intelligence). Moreover, VNU-UET and UEC will collect the vital-sign data with the infection screening system and the ground-truth devices for Healthy subjects at VNU-UET, Vietnam.

    EEG signal processing from the computer vision perspective

    In this work, we study the processing of EEG signals in the image domain, i.e., visualizing the signal in the binary image and applying computer vision techniques for signal smoothing and classification. Some research questions are being investigated: 1. How well can we smooth the signal in the image domain? Here, we plot the interested […]

    Vision-based crack detection with crack propagation modeling

    In this work, the propagation of cracks on some materials, such as concrete, is analyzed, the best-fit model of which is employed for vision-based crack detection. Some research questions are being investigated: 1. What is the correlation between simulated crack propagation and real-world crack? Here, we measure the fitting errors between best-fit regression models of […]

    Machine learning based beacon placement optimization for indoor robots localization

    Indoor localization systems usually consist of transceiver with fixed positions, which are called beacons. These beacons act as landmarks for localizing objects that need to be positioned. One can easily see that the positions of beacons have a great impact on the performance of the localization system. The problem of beacon placement optimization is to […]
