      Selvaraj, Jerritta; Murugappan, Muthusamy, Dr.; Wan Khairunizam, Wan Ahmad, Dr.; Sazali, Yaacob, Prof. Dr. (Taylor & Francis, 2014-04)
      Higher order statistics (HOS) is an efficient feature extraction method used in diverse applications such as bio signal processing, seismic data processing, image processing, sonar, and radar. In this work, we have ...

    • Frequency study of facial electromyography signals with respect to emotion recognition 

      Selvaraj, Jerritta; Murugappan, Muthusamy, Dr.; Wan Khairunizam, Wan Ahmad, Dr.; Sazali, Yaacob, Prof. Dr. (Walter de Gruyter GmbH, 2014-01)
      Emotional intelligence is one of the key research areas in human-computer interaction. This paper reports the development of an emotion recognition system using facial electromyogram (EMG) signals focusing the ambiguity ...

    • In vitro evaluation of finger's hemodynamics for vein graft surveillance using electrical bio-impedance method 

      Lee, Hoi Leong; Shahriman, Abu Bakar, Dr.; Sazali, Yaacob, Prof. Dr.; Zuradzman, Mohamad Razlan, Dr.; Wan Khairunizam, Wan Ahmad, Dr.; Zunaidi I.B; Cheng, Ee Meng, Dr.; Siti Khadijah, Za'aba, Dr.; Shafriza Nisha, Basah, Dr.; Mohd Afendi, Rojan, Dr.; Sharifah Roohi, Syed Waseem Ahmad (American-Eurasian Network for Scientific Information (AENSI), 2014-03)
      Electrical bio-impedance measurement has great potential in many biomedical applications including vein graft surveillance. Studies have shown that thrombosis was the major cause of the vein graft failure. The meticulous ...

    • Performance comparison of daubechies wavelet family in Infant cry classification 

      Saraswathy, J; Hariharan, Muthusamy; Vijean, Vikneswaran; Sazali, Yaacob, Prof. Dr.; Wan Khairunizam, Wan Ahmad, Dr. (IEEE Conference Publications, 2012)
      Infant cry is a non-stationary, loud, high-pitched signal made by infants in response to certain situations. This acoustic signal can be used to identify physical or psychology status of infant. The aim of this work is to ...
