Motion Energy Analysis (MEA) is an objective automated method that continuously monitors the amount of movement occurring in pre-defined regions of interest.
This page includes information on tool availability and possible applications.
The basic prerequisites for MEA are a static camera position, stable light conditions, and digitized film material.
