Zejian Feng, Martina Karaskova, Marwa Mahmoud

Abstract: Sheep, being vulnerable prey species, frequently conceal overt signs of pain, which can lead to neglect of their welfare. These signs of pain are usually indicators of diseases that can escalate or becomes contagious. Recent work have developed computational methods for automatic detection of pain from sheep faces for early estimation of diseases. This paper presents an open source tool ‘Open Sheep Face’ that implements various techniques grounded in prior research as a comprehensive pipeline for sheep face detection, landmarks localisation, pose estimation and pain level estimation.
