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)
1 Department of Automatic Control Engineering, Feng Chia University, Taiwan, R.O.C. 2 Graduate Institute of Networking and Communication Engineering, Chaoyang University of Technology, Taichung, Taiwan,R.O.C. Abstract The main purpose of this study is to present a novel personal authentication approach that uses the electrocardiogram (ECG) signal. Because(More)
In traditional Chinese tongue diagnosis, inspection of the sublingual veins has been developed as a new diagnostic examination method especially for determining blood stasis. The main purpose of this research is to develop a computerized inspection system, used to quantitatively extract the chromatic and geometrical properties of sublingual veins. A method(More)
In this paper, a new method for an improved image password lock system by tracing position information of the pupil is described. The present technology relates to an efficient auto-detecting function, and in particular, to an image password lock system, which can provide the benefits of a novel password input mode without any contact. In this system, a PC(More)
Cerebral autoregulation (CA) was assessed by chaotic analysis based on mean arterial blood pressure (MABP) and mean cerebral blood flow velocity (MCBFV) in 19 diabetics with autonomic neuropathy (AN) and 11 age-matched normal subjects. MABP in diabetics dropped significantly in response to tilting (91.6 ± 14.9 vs. 74.1 ± 13.4 mmHg, P < 0.05). Valsalva ratio(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)
A self-organizing classification system for the arterial pressure pulse based on the ART2 (adaptive resonance theory) network was developed. The system consists of a preprocessor and an ART2 recognition network. The preprocessor removes the arterial pressure pulse servo component signals from Finapres, detects the systolic pressure points and divides the(More)
Disturbances of impulse formation and conduction may occur anywhere in the human heart. The most common cardiac arrhythmia is the ventricular premature beat. Premature beats may be atrial, atrioventricular (A-V) junctional or ventricular in origin, and may be found in apparently healthy individuals. However, premature beats may become clinically significant(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)
