This research is aimed at building a computerized tongue examination system (CTES) based on computerized image analysis for the purpose of quantizing the tongue properties in traditional Chinese medical diagnosis. The chromatic algorithm is developed to identify the colors of the tongue and the thickness of its coating. The textural algorithm is used to(More)
Time domain cross-correlation analysis of pre-filtered mean arterial blood pressure (MABP) and mean cerebral blood flow velocity (MCBFV) was applied to assess the cerebral autoregulation (CA). Beat-to-beat time series of spontaneous arterial blood pressure and cerebral blood flow velocity were obtained from 13 young normal volunteers with the Finapres(More)
The goal of this work is to propose novel acoustic parameters of voice for the purpose of providing a quantitative analysis of auscultation in traditional Chinese medical diagnosis. There is rare amount of available literature related to this topic. Four novel acoustic parameters, the average number of zero-crossings, the variations in local peaks and(More)
An eye mouse interface that can be used to operate a computer using the movement of the eyes is described. We developed this eye-tracking system for eye motion disability rehabilitation. When the user watches the screen of a computer, a charge-coupled device will catch images of the user's eye and transmit it to the computer. A program, based on a new(More)
In this paper, we use the optical-type eye tracking system to control powered wheelchair. The userís eye movements are translated to screen position using the optical-type eye tracking system. The pupil-tracking goggles with a video CCD camera and a frame grabber analyzes a series of human pupil images when the user is gazing at the screen. A new(More)
The main purpose of this study is to present a novel personal authentication approach that uses the electrocardiogram (ECG) signal. Because the ECG signal varies from person to person, it can be used as a new biometric for individual verification. The discrete wavelet transform was applied for extracting features. These wavelet coefficients derived from(More)
The evolution of information technology over the last decade has brought opportunities to improvements in the state of art of medical services. One scenario is that a patient's digital health record can easily be shared among hospitals and medical centers via internet, enabling the examination performed in one location while clinical diagnosis be done by(More)
