ECG
The early detection of arrhythmia is very important
for the cardiac patients. This is done by analyzing the
electrocardiogram (ECG) signals and extracting some features
from them. These features can be used in the classification of
different types of arrhythmias. In this paper, we present three
different algorithms of features extraction: Fourier transform
(FFT), Autoregressive modeling (AR), and Principal Component
Analysis (PCA). The used classifier will be Artificial Neural
Networks (ANN). We observed that the system that depends on
the PCA features give the highest accuracy. The proposed
techniques deal with the whole 3 second intervals of the training
and testing data. We reached the accuracy of 92.7083
compared to 84.4 for the reference that work on a similar
data.

这种方法一方面将像素的灰度值分散,可以分辨图象中比较细节的内容;另一方面,将图
象的灰度变化控制在一定范围之内,抑制了噪声的产生,较大程度上地保留了原始图象的亮度.(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)
