Area of Science:

  • Veterinary Medicine
  • Computer Vision
  • Animal Behavior

Background:

  • Facial landmarks are crucial for human affective computing and are gaining traction in animal studies.
  • Geometric morphometrics using facial landmarks objectively assess cat expressions, aiding pain recognition and breed morphology studies.
  • Manual landmark annotation is time-consuming, limiting data for machine learning and real-time applications.

Purpose of the Study:

  • To develop and evaluate fully automated AI pipelines for cat facial analysis tasks.
  • To assess the effectiveness of end-to-end landmark-based systems for practical applications in cats.
  • To explore the potential of AI-driven facial analysis for breed and cephalic type recognition, and pain assessment.

Main Methods:

  • Developed AI pipelines for automated facial landmark detection in cats.
  • Utilized two previously collected datasets of cat faces for analysis.
  • Applied the pipelines to three benchmark tasks: automated cat breed recognition, cephalic type recognition, and pain recognition.

Main Results:

  • The fully automated pipelines achieved 75% accuracy in cephalic type recognition.
  • The pipelines reached 66% accuracy in pain recognition.
  • These results indicate the viability of automated landmark-based approaches for cat facial analysis.

Conclusions:

  • Landmark-based AI approaches show significant promise for automated pain assessment in cats.
  • These methods can facilitate objective morphological explorations in feline species.
  • Fully automated systems offer a practical solution for large-scale cat facial analysis and welfare monitoring.
