The core methodology centers on a hierarchical adaptive framework designed for robust camel breed classification. This two-stage approach first distinguishes between Arabian and Non-Arabian camels, then proceeds to fine-grained classification of specific Arabian breeds. To overcome challenges like visual similarity and data imbalance, the model employs online data augmentation and class-balanced focal loss, ensuring balanced learning and enhanced generalization. A novel multi-stream architecture, integrating global context, local features, and semantic cues, is utilized to optimize feature extraction. This holistic design ensures comprehensive analysis of visual characteristics, from overall body structure to subtle textural differences.

Key findings highlight the superior performance of the hierarchical multi-stream model, especially using DenseNet121. In binary classification, the model achieved an impressive 98% accuracy. For the more challenging multi-class task identifying specific Arabian breeds, it reached 76% accuracy, outperforming other state-of-the-art CNNs. Ablation studies confirmed that the multi-stream design significantly enhances accuracy and macro F1-score across all classification metrics. Grad-CAM visualizations provide crucial interpretability, showing the model accurately focuses on breed-defining anatomical features such as hump shape, neck profile, and coat texture, validating its reliance on biologically meaningful cues rather than background noise.

Interpreting AI Decisions: Grad-CAM for Camel Classification
Grad-CAM visualizations proved essential for understanding model behavior. For Arabian camels, the model primarily focused on the neck, head, and overall posture, reflecting their characteristic elegance and curvature. In contrast, for Non-Arabian camels (Bactrian), attention centered on their broader humps and robust body shapes. This confirmed that the AI model correctly learns and relies on biologically meaningful features, enhancing transparency and trust in its predictions, especially critical for fine-grained distinctions and reducing reliance on spurious background cues.

Future work aims to expand the dataset to include a wider variety of breeds, age groups, sexes, and health statuses, incorporating real-world variations. Exploring advanced generative models like GANs could synthesize diverse data, addressing current dataset imbalances. Integrating transformer-based vision models is a promising avenue for improving feature representation and context understanding. Additionally, evaluating alternative interpretability techniques such as Score-CAM or Layer-wise Relevance Propagation (LRP) will further enhance model transparency. These advancements will boost the practical utility and scalability of intelligent camel classification systems for global livestock management.
