Image analysis to measure activity index of animals

The objective of the study was to present a method to quantify the behavioural response of animals to their micro-environment by using a camera system and a digitiser board. An algorithm was developed for analysing images and calculating activity, occupied zone and boundary of the animals. The developed method was tested on 3 different applications and animals. In the first application, the behavioural responses of broiler chickens to their thermal environment was measured. In the second application behavioural responses of pigs to their thermal environment were measured. In the third application, the response of water fleas to a chromium pollution was measured using the developed technique. Based on the experimental results, it can be concluded that the developed image analysis technique can be employed to quantify the behavioural responses of the tested animals to their micro-environment, in an easy and accurate way.
