What cat is that? A re-id model for feral cats
Victor Caquilpan

TL;DR
This paper develops a specialized re-identification model, PPGNet-Cat, for feral cats using camera trap images, achieving high accuracy and demonstrating its effectiveness for wildlife monitoring and invasive species management.
Contribution
It adapts a pose-guided re-ID network originally for tigers to feral cats, incorporating contrastive learning techniques for improved identification performance.
Findings
Achieved a mean Average Precision of 0.86
Attained a rank-1 accuracy of 0.95
Demonstrated the model's suitability for feral cat re-ID
Abstract
Feral cats exert a substantial and detrimental impact on Australian wildlife, placing them among the most dangerous invasive species worldwide. Therefore, closely monitoring these cats is essential labour in minimising their effects. In this context, the potential application of Re-Identification (re-ID) emerges to enhance monitoring activities for these animals, utilising images captured by camera traps. This project explores different CV approaches to create a re-ID model able to identify individual feral cats in the wild. The main approach consists of modifying a part-pose guided network (PPGNet) model, initially used in the re-ID of Amur tigers, to be applicable for feral cats. This adaptation, resulting in PPGNet-Cat, which incorporates specific modifications to suit the characteristics of feral cats images. Additionally, various experiments were conducted, particularly exploring…
