Comparison of performance using Daubechies Wavelet family for facial expression recognition
(Institute of Electrical and Electronics Engineers (IEEE), 2010-05-21)This paper investigates the performance of a Daubechies Wavelet family in recognizing facial expressions. A set of luminance stickers were fixed on subject's face and the subject is instructed to perform required facial ... -
Diagnosis of vocal fold pathology using time-domain features and systole activated neural network
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-03-06)Due to the nature of job, unhealthy social habits and voice abuse, the people are subjected to the risk of voice problems. It is well known that most of vocal fold pathologies cause changes in the acoustic voice signal. ... -
Luminance sticker based facial expression recognition using discrete wavelet transform for physically disabled persons
(Springer Science+Business Media, LLC., 2012)Developing tools to assist physically disabled and immobilized people through facial expression is a challenging area of research and has attracted many researchers recently. In this paper, luminance stickers based facial ...
