Ecg Signal Generator Based on Geometrical Features
Electrocardiograms are widely used in biomedical signal processing to diagnose abnormal heart functioning. Many algorithms have been constructed to analyse, measure and compress these signals. These methods are hard to test because real ECG signals are distorted by several types of noise. In this paper we present an algorithm which generates realistic synthetic ECG signals. This algorithm, amon...
متن کاملSpeech Signal Compressed Sensing Based on K- Svd Adaptive Dictionary
This paper proposes a novel and successful method for speech signal compressed sensing based on KSingular Value Decomposition (K-SVD) algorithm. K-SVD is an iterative method that alternates between sparse representation of the train samples based on the current dictionary and a process of updating the dictionary atoms to better fit the speech data. The presented K-SVD algorithm is applied here ...
متن کاملPost - Exercise Ecg Pre - Exercise Ecg
One hundred and ten patients with chest pain syndromes and resting electrocardiograms demonstrating ST-T abnormalities and/or prior transmural myocardial infarctions were studied by means of the Master's two-step exercise test and selective coronary cine arteriography. Criteria for negativity were modified so that subjects with postexercise heart rates less than 110 beats/min, who did not devel...
متن کاملResearch on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
متن کاملWavelet Transform Based Ecg Signal Filtering Implemented on Fpga
Filtering electrocardiographic (ECG) signals is always a challenge because the accuracy of their interpretation depends strongly on filtering results. The Discrete Wavelet Transform (DWT) is an efficient, new and useful tool for signal processing applications and it’s adopted in many domains as biomedical signal filtering. This transform came about from different fields, including mathematics, ...
