CATS is a signal processing technique and framework for detecting and denoising sparse signals in the time-frequency domain. Particularly, very useful for processing earthquakes. This work is still in progress, and the package is under active development. Soon, here will be links to our papers/preprints.
- Versatile. Any sparse signals in the time-frequency domain can be localized by CATS.
- Flexible. Fast detection with STFT or more accurate denoising with CWT.
- Fast and accurate. Here will be links to our papers showing this.
- Comprehensive quality control.
- Autotunable parameters with direct physical interpretation.
- Easy visualization of all intermediate workflow steps.
- Collected cluster statistics allow for fine-grained QC and classification of signals.
To install the package:
