Combining this method with identification techniques
such as using ear tags (Allen et al.,2008), animal
husbandry management can be improved.
However,there are still challenges to use the proposed technique in practical
settings. Due to experimental requirements, stocking
density in images used in this study was as low as 1.23 pig/m2
while in a real farm setting, stocking density will be as
high as 1.67 pig/m2 (Schinkel et al.,2009).
