  - 'Lagrangian coherent structures (LCSs) are widely recognized as playing a significant
    role in turbulence dynamics since they can control the transport of mass, momentum
    or heat. However, the methods used to identify these structures are often based
    on ambiguous definitions and arbitrary thresholding. While LCSs theory provides
    precise and frame-indifferent mathematical definitions of coherent structures,
    some of the commonly used extraction algorithms employed in the literature are
    still case-specific and involve user-defined parameters. In this study, we present
    a new, unsupervised extraction algorithm that enables the extraction of rotational
    LCSs based on Lagrangian average vorticity deviation from an arbitrary 3D velocity
    field. The algorithm utilizes two alternative methods for the identification of
    the LCS core (ridge): an unsupervised clustering method and a streamline-based
    method. In a subsequent step, the ridge curve is parametrized through a pruning
    procedure of minimum spanning tree graphs. To assess the effectiveness of the
    algorithm, we test it on two cases: (i) direct numerical simulations of forced
    homogeneous and isotropic turbulence and (ii) three-dimensional Particle Tracking
    Velocimetry experiments of a turbulent gravity current.@eng'
