The aim of our work is to realize the implementation of a real-time image rotation on FPGA's board. The method we used is based on a B-spline interpolator. The integration capicity of FPGAs is relatively weak, so the difficulty in this problem is to determine the right coding of the rotation filter while keeping a good accuracy on filtering output. In this article, we remind a few definitions about...
One of the way to extract edges uses the fast wavelet transform algorithm. This technique allows the detection of multiscale edge and is used to detect all the details which are in a picture by modifying the scale. The real time application for edge detection involves the implementation of the algorithm on an integrated circuit like an FPGA and the development of an appropriated board. This article...
Complexity of R-R intervals (RR) and systolic arterial pressure (SAP) variability were computed to detect the aging process influence over cardiovascular control in resting supine (REST) and standing position (STAND). One hundred healthy subjects were divided into five groups (n=20 for each), according to age: 21–30; 31–40; 41–50; 51–60; 61–70. The RR and SAP series were recorded for 15 minutes at...
Aging causes changes in cardiovascular control. The aim of the study was to analyze the effects of age on baroreflex sensitivity of healthy individuals of different ages, through cross-spectral analysis. One hundred and ten individuals divided into 5 age groups were evaluated. Heart period (HP) and systolic blood pressure (SBP) were derived from ECG and blood pressure signals recorded simultaneously...
