Prediction of Sow Farrowing Onset Time Using Activity Time Series Extracted by Optical Flow Estimation

Prediction of Sow Farrowing Onset Time Using Activity Time Series Extracted by Optical Flow Estimation

Sow farrowing is a critical stage in pig farming, and predicting its onset can improve sow health and piglet survival. This study proposes a method based on optical flow estimation and time-series forecasting to predict sow farrowing onset. The RAFT optical flow algorithm is applied to visible-light...
