A rapid non-iterative proper orthogonal decomposition based outlier detection and correction for PIV data. Higham, J., E., Brevis, W., & Keylock, C., J. Measurement Science and Technology, 27(12):125303, 4, 2016. Website doi abstract bibtex 2 downloads The present work proposes a novel method of detection and estimation of outliers in particle image velocimetry measurements by the modification of the temporal coefficients associated with a proper orthogonal decomposition of an experimental time series. Using synthetic outliers applied to two sequences of vector fields, the method is benchmarked against state-of-the-art approaches recently proposed to remove the influence of outliers. Compared with these methods, the proposed approach offers an increase in accuracy and robustness for the detection of outliers and comparable accuracy for their estimation.
