An automatic system for the detection of dairy cows lying behaviour in free-stall barns

Abstract: In this paper, a method for the automatic detection of dairy cow lying behaviour in free-stall barns is proposed. A computer visionbased system (CVBS) composed of a video-recording system and a cow lying behaviour detector based on the Viola Jones algorithm was developed. The CVBS performance was tested in a head-to-head free stall barn. Two classifiers were implemented in the software component of the CVBS to obtain the cow lying behaviour detector. The CVBS was validated by comparing its detection results wi… Show more

“…Images afford automated and nonintrusive observations. Their potential has been demonstrated in diverse realms of agricultural engineering, such as, the detection of dairy cows lying behaviour (Porto et al, 2013), the determination of the size distribution of wood chips (Febbi et al, 2013), the assessment of basal shear stress in debris-flow mixtures (D'Agostino et al, 2013), and the measurement of kinematic properties of granular flows (Gollin et al, 2015). With regards to fluid flow monitoring, digital images have been traditionally adopted in fluid dynamics laboratories as powerful quantitative fluid visualisation techniques.…”

“…Analysis of digital images obtained from video-recordings is an effective tool for studying livestock behaviors under various environmental conditions (Porto et al, 2013 among the image analysis methods considered. Digital image analysis methods can work well under the following conditions: the animal images have a high contrast with the background to allow for image segmentation; the background is constant or has constant brightness variations to extract the animal features from the image; the color range applied to the animal is different from the background (Porto et al, 2013). However, image segmentation in digital RGB image can be problematic under real farm conditions due to dynamic background restrictions, such as dim or uneven light intensity of the house and varying floor status.…”
