摘要

Traditional technologies provide significant integration opportunities for wildlife conservation and re-identification; nonetheless, we necessitate more sophisticated solutions to address extensive areas and substantial animal populations. The research introduced a scalable framework for wildlife re-identification that integrates SimCLR, a self-supervised representation learning method, with supervised fine-tuning utilizing a ResNet-50 backbone on the WildlifeReID-10k dataset, which comprises 37 animal classes. The paper addresses class imbalance by employing weighted losses and data augmentation techniques to maintain fine-grained identity clues in wildlife photos. The suggested model attained an accuracy of 89.81%, surpassing existing models such as VGG16 and DenseNet121 by 6–11%. It also demonstrated a high F1-score, along with individual precision, and recall for each class, despite a few misclassified data. The research elucidates the superiority of SimCLR and ResNet-50 compared to alternative models, with the primary objective of enhancing the dependability of non-invasive species monitoring, even in varying lighting and environmental conditions. These enhancements can fortify conservation planning and facilitate superior management. The research elaborates on the various constraints and challenges that may emerge when using the methodologies and algorithms in wildlife studies, including computational expenses and fluctuating environmental circumstances. The research has addressed several constraints related to underrepresented species, environmental variables like lighting and occlusion, and dependence on visual modalities, as well as prospects.
