matlab实现的图像标注开源代码，极有参考价值。(matlab implementation of image annotation open source code, and a valuable reference.)

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.

Models of the distribution are critical in providing high quality of service. A number of researchers have observed over the years that the distribution pattern is complex. In the subsequent section, the effect of shift given to the feedback signal are analyzed.
