Feature Detection and Extraction Using Wavelets, Part 2: Feature Extraction Using Wavelets

Use the Discrete Wavelet Transform in MATLAB^®  to extract spectral features from real-world signals. The goal of this demo is to demonstrate how you can use wavelet transform to extract R waves from an EKG signal to enhance peak detection and compute heart rate. Refer to Feature Detection Using Wavelets - Part 1 for more information about how wavelet transform can be used to identify spectral features.
