    • Monitoring surge-type glacier velocities using Pixel Offset Tracking Small Baseline Subset method with Robust Trend-Outlier Decomposition

    • “A signal processing method based on Robust Trend Outlier Decomposition (RTOD) is proposed to address the problem of severe interference from outliers in the traditional offset tracking small baseline set method for three-dimensional temporal flow velocity monitoring of leaping glaciers. This method improves the reliability and accuracy of flow velocity time series and introduces its research progress in the field of leaping glacier monitoring. The research team has established the RTOD-PO-MSBAS and RTOD-3D-POSBAS algorithm systems, providing a solution to the problem of removing temporal flow velocity outliers in leaping glaciers.”
