Area of Science:

  • Animal behavior analysis
  • Veterinary technology
  • Machine learning applications

Background:

  • Pet health monitoring is crucial but challenging due to reliance on external observation.
  • Assessing internal conditions and distinguishing behavior from physiological changes (e.g., heart rate) is difficult.
  • Current monitoring methods often lack accuracy or require integration with behavioral data.

Purpose of the Study:

  • To develop and evaluate an animal monitoring system using video image analysis.
  • To detect typical and anomalous activities in pets, specifically hamsters.
  • To differentiate between behavioral and internal state changes for improved health assessment.

Main Methods:

  • Utilized mask R-CNN for feature extraction from top-view cage video images.
  • Analyzed behavioral information and inferred internal states.
  • Developed an alert system for detecting unusual hamster behavior.

Main Results:

  • The system successfully extracted and analyzed hamster behavioral features.
  • Demonstrated ability to detect typical daily activities and anomalous behaviors.
  • Effectively discriminated between behavioral and internal changes, even when exposed to external stimuli like loud sounds.

Conclusions:

  • The proposed video analysis system offers a promising approach for non-invasive animal health monitoring.
  • Accurate detection of behavioral and internal states can enhance pet welfare and early illness detection.
  • Future work will focus on enhancing measurement accuracy for subtle movements.
