Example of ROI from the grabbed image to the fully constructed zone in EthoVision XT (left to right). Note that the parallel red floor markings were used to correctly position the Styrofoam columns. The zones were delineated by drawing lines in EthoVision XT, connecting the indicators (i.e., red tape) on top of the Styrofoam columns. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article).
