For the large-scale, intensive farming environment, the cow＇s behavior and activity is an important indicator to determine whether estrus which is confirmed by numerous academic and scientific research. Usually the cow＇s behavior decision-making methods are using the single point of data to classify behavior. However the cow＇s |
