Fetal Heart Rate (FHR) Estimation from 3.3 MHz 1D Doppler Transducer written in Matlab, Written by David Springer, Lisa Stroux and Camilo E. Valderrama under the supervision of Gari Clifford Please reference: Camilo E. Valderrama, Lisa Stroux, Nasim Katebi, Elianna Paljug, Faezeh Marzbanrad, Gari D. Clifford. An open source autocorrelation-based method for fetal heart rate estimation from one-dimensional Doppler ultrasound, Physiological Measurement, 2019 (In Press) To test if the files give the expected result please, first run the script: demo_fhr_us.m You should see: Name of recording: test1 Total difference along all windows: 0.000000 bpm Score comparison: Exact match with gold standard output Name of recording: test2 Total difference along all windows: 0.000000 bpm Score comparison: Exact match with gold standard output There may be a small difference, but no more than a fraction of one BPM. To estimate FHR from test signals located in ../Recording folder. run script: estimatingFHR.m The FHR estimation function is called: getFRH.m Toolboxes required (using "license('inuse')"): econometrics_toolbox signal_blocks signal_toolbox Tested with: MATLAB Version: 9.3.0.867777 (R2017b) Update 7 Operating System: Mac OS X Version: 10.14 Build: 18A391 Java Version: Java 1.8.0_144-b01 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode MATLAB Version 9.3 (R2017b) Simulink Version 9.0 (R2017b) Audio System Toolbox Version 1.3 (R2017b) Bioinformatics Toolbox Version 4.9 (R2017b) Communications System Toolbox Version 6.5 (R2017b) Computer Vision System Toolbox Version 8.0 (R2017b) Control System Toolbox Version 10.3 (R2017b) Curve Fitting Toolbox Version 3.5.6 (R2017b) DSP System Toolbox Version 9.5 (R2017b) Database Toolbox Version 8.0 (R2017b) Datafeed Toolbox Version 5.6 (R2017b) Econometrics Toolbox Version 4.1 (R2017b) Embedded Coder Version 6.13 (R2017b) Financial Instruments Toolbox Version 2.6 (R2017b) Financial Toolbox Version 5.10 (R2017b) Fixed-Point Designer Version 6.0 (R2017b) Fuzzy Logic Toolbox Version 2.3 (R2017b) Global Optimization Toolbox Version 3.4.3 (R2017b) HDL Coder Version 3.11 (R2017b) Image Acquisition Toolbox Version 5.3 (R2017b) Image Processing Toolbox Version 10.1 (R2017b) Instrument Control Toolbox Version 3.12 (R2017b) LTE System Toolbox Version 2.5 (R2017b) MATLAB Coder Version 3.4 (R2017b) MATLAB Compiler Version 6.5 (R2017b) MATLAB Compiler SDK Version 6.4 (R2017b) Mapping Toolbox Version 4.5.1 (R2017b) Neural Network Toolbox Version 11.0 (R2017b) Optimization Toolbox Version 8.0 (R2017b) Parallel Computing Toolbox Version 6.11 (R2017b) Partial Differential Equation Toolbox Version 2.5 (R2017b) Phased Array System Toolbox Version 3.5 (R2017b) Risk Management Toolbox Version 1.2 (R2017b) Robotics System Toolbox Version 1.5 (R2017b) Signal Processing Toolbox Version 7.5 (R2017b) SimBiology Version 5.7 (R2017b) Simscape Version 4.3 (R2017b) Simscape Multibody Version 5.1 (R2017b) Simulink Coder Version 8.13 (R2017b) Simulink Control Design Version 5.0 (R2017b) Stateflow Version 9.0 (R2017b) Statistics and Machine Learning Toolbox Version 11.2 (R2017b) Symbolic Math Toolbox Version 8.0 (R2017b) System Identification Toolbox Version 9.7 (R2017b) Tracking and Sensor Fusion Toolbox Version 1.0 (R2017b) Trading Toolbox Version 3.3 (R2017b) Wavelet Toolbox Version 4.19 (R2017b)
