This paper proposed the method that can efficiently detect the transient component existing in the multi-channel audio signal and accordingly extract spatial cues in order to improve the performance of the spatial cue based multi-channel audio coding. The proposed transient signal detection algorithm was implemented to use energy as well as the input signal envelope so as to successfully detect both...
We have developed a knowledge based approach for arterial stiffness estimation. The proposed new approach reliably estimates arterial stiffness based on the analysis of age and heart rate normalized reflected wave arrival time. The proposed new approach reduces cost, space, technical expertise, specialized equipment, complexity, and increases the usability compared to recently researched noninvasive...
The digital volume pulse (DVP) is a physiological signal obtained from the photoplethysmography. Since the photoplethysmography measures volumetric changes of blood occurred by heart contraction and properties of blood vessels, DVP contains several feature parameters that reflect cardiovascular events, such as arterial stiffness. In order to extract these parameters, a number of algorithms have been...
Many previous studies suggested that the digital volume pulse (DVP) can be used to estimate arterial stiffness. The DVP waveform can be rapidly acquired by measuring reflection or absorption of red light (or infrared light) across the photoplehtysmography (PPG). Because of the nature of its measuring principle, the DVP is often contaminated by noise from light sources, such as sunlight, and disturbances...
