The so-called ‘median test’ is the most widely used
method for outlier detection in post-interrogation validation
of PIV data (Westerweel 1994).The principle and
effectiveness of the original method was demonstrated for
homogeneous and isotropic turbulence,for which a single
outlier detection threshold can be applied to the entire
data set on the basis of the velocity fluctuation intensity.
The original paper contains an appendix that describes
the application of the method for general (turbulent) flow
fields,but this recipe is quite elaborate and requires a
priori information of the flow field; this procedure
has—to the best of the authors knowledge—never been
actually applied in practice.Instead,it is quite common to
apply a single detection threshold in the evaluation of
(strongly) inhomogeneous flow data.For example,in a
PIV measurement of a submerged turbulent jet (see
