Automatic identification of marked pigs in a pen using image pattern recognition

► Pigs are localised in a pen using ellipse fitting modelling. ► We paint fattening pigs with basic patterns to differentiate them. ► We introduce an elegant way to identify pigs in a farm pen. ► Algorithms are presented to detect location of pigs within a pen. ► We can analyse specific behaviours in pigs such as resting using identification and therefore localisation.
