Altimetry: estimation of the Sea Level Anomaly (SLA) slope

Altimetry: estimation of the Sea Level Anomaly (SLA) slope

TeSA is working on the estimation of Sea Level Anomaly (SLA) signal characteristics in collaboration with the CNES (French Space Agency), with a particular focus on slope spectral estimation. A new method called "ARWARP", combining frequency warping, autoregressive modeling and linear regression has been presented in IGARSS 2020, showning interesting performance, compared to the usual method based on the periodogram.

P and T wave detection and estimation in ECG signals

TeSA has brought his statistical signal processing expertise in electrocardiogram (ECG) processing, through the PhD of Chao Lin (July 2012). In order to help diagnosis, it is of interest to automatically analyze ECGs and to detect the different waveforms (P, QRS, T waves). Bayesian estimation/detection algorithms suitable for P and T wave analysis in ECG signals have been successfully proposed during the PhD. The freely available Matlab codes have been published in the IEEE Trans on Biomedical Engineering 2010 journal and at IEEE ICASSP 2011 conference.

Extract the legend of a MATLAB figure

Extract the legend of a MATLAB figure

This script extracts the legend from a MATLAB figure. For example, if an important legend corresponds to several figures, this script makes it possible to isolate it in order to export it to make it appear next to the figures in a document.
