We consider local vortex identification in turbulent flows using the two kinematic parameter framework of Chakraborty, Balachandar & Adrian (2005) (hereafter referred to as CBA05). The inter-relationships between the various local criteria are summarized and the notion of 'equivalent thresholds' is applied to two canonical turbulent flows: sphere wake and channel flow. Remarkably similar vortex structures are extracted using the 'equivalent thresholds'.
