Strain mapping using cepstral transformation
We recommend using the cepstral analysis code within the Anaconda framework. It is also recommended to create a new virtual environment, follow the instructions below.
conda update conda
conda create -n cepstral
conda activate cepstral
Required packages - numpy, matplotlib, scipy, scikit-learn, ipympl, tqdm, opencv. These can be installed by running the following commands in the conda terminal.
conda install -c conda-forge matplotlib
conda install -c conda-forge scipy
conda install -c conda-forge ipympl
conda install -c conda-forge scikit-learn
conda install -c conda-forge tqdm
conda install -c conda-forge notebook
conda install -c conda-forge opencv
conda update --all
The MATLAB version of the code can be found at https://github.com/muller-group-cornell/PC-STEM. The paper introducing the exit wave power cepstrum is : E. Padgett, M. E. Holtz, P. Cueva, Y. T.
