Area of Science:

  • Animal Science
  • Computer Vision
  • Machine Learning

Background:

  • Automatic pig behavior recognition is essential for improving animal welfare and livestock breeding efficiency.
  • Current methods often rely on manual observation or computationally intensive deep learning models, leading to inefficiencies.
  • There is a need for more efficient and accurate automated systems for monitoring pig behavior.

Purpose of the Study:

  • To develop a novel deep mutual learning enhanced two-stream approach for accurate pig behavior recognition.
  • To overcome the limitations of traditional methods, such as time consumption and low efficiency.
  • To improve the robustness and performance of pig behavior recognition systems.

Main Methods:

  • Proposed a two-stream architecture incorporating red-green-blue (RGB) and flow streams for behavior recognition.
  • Implemented a deep mutual learning framework with collaborative student networks within each stream.
  • Utilized weighted fusion of RGB and flow branch outputs to enhance recognition performance.

Main Results:

  • The proposed model achieved state-of-the-art pig behavior recognition accuracy of 96.52%.
  • Demonstrated superior performance compared to existing models, surpassing them by 2.71%.
