matlab如何敲代码-heartrack:一种从腕式PPG数据检测心脏跳动率的小波方法。从纸上：

# Introduction I just Finish 2015 IEEE Signal Processing Cup, and here is an Heart Rate Tracking algorithm using Wrist-Typed PPG Signal. **Notice** > This is **Not** the exact algorithm we used in the paper: [http://web.cse.ohio-state.edu/~tke/doc/MICROST.pdf](http://web.cse.ohio-state.edu/~tke/doc/MICROST.pdf), which gave better result than this one, but the idea and procedure are the same. <br> <br> ## How to Run 1. Download the code 2. Add Path in Matlab 3. change variable in init.m (where to save pictures) Then ```matlab runall_train %% run algorithm on all training data runall_test %% run algorithm on all testing data ``` You will see the result. <br> <br> ## About the algorithm - 7-order haar wavelet transform for signal preprocess - Four Heuristic Unit for tracking Frequency Peak - **Memory Rule**: for heart rate could not change too sharply - **Magnitude Rule**: select the larger peak - **Wavelet Rule**(only used in the first frame): When the heart rate peak submerges in motion peaks, the wavelet preprocess may make it emerges. - **Acceleration Rule**: When the subject speeds up, the heart rate tends to grow And each rule corresponds to a M-file. <br> <br> ### More - A Post in My Blog: [Link](http://xyzhang.me/algorithm/dsp/2015/01/14/heart-rate-tracking.html) (in Chinese) - More Intro: TODO <br> <br> ## Data The Data used here comes from [HERE](http://www.zhilinzhang.com/spcup2015/data.html) with copyrights.
