Abstract
As farms are getting bigger with more animals,

less manual supervision and attention can be given the animals

on both group and individual level. In order not to jeopardize

animal welfare, automated supervision is in some way already

in use. Function and control of ventilation is already in use in

modern pig stables, e.g. by the use of sensors for temperature,

relative humidity and malfunction connected to alarm. However,

by measuring continuously directly on the pigs, more information

and more possibilities to adjust production inputs would be

possible. In this work, the focus is on a key image processing

algorithm aiding such a continuous system -... (More)
As farms are getting bigger with more animals,

less manual supervision and attention can be given the animals

on both group and individual level. In order not to jeopardize

modern pig stables, e.g. by the use of sensors for temperature,

relative humidity and malfunction connected to alarm. However,

by measuring continuously directly on the pigs, more information

and more possibilities to adjust production inputs would be

possible. In this work, the focus is on a key image processing

algorithm aiding such a continuous system - segmentation of pigs

in images from video. The proposed solution utilizes extended

state-of-the-art features in combination with a structured prediction

framework based on a logistic regression solver using elastic

net regularization. Objective results on manually segmented

images indicate that the proposed solution, based on learning,

performs better than approaches suggested in recent publications

addressing pig segmentation in video. (Less)
