Table 2. Summary of RGB imaging techniques used to improve health monitoring and management practices in pig farming

Application	Description	Benefits
Disease symptom detection	RGB imaging detects visual symptoms such as skin lesions, abnormal breathing, and discoloration.	Enables early identification of diseases such as respiratory issues, skin infections, and injuries.
Tracking disease progression	Continuous imaging tracks changes in symptoms over time, helping monitor recovery or deterioration.	Assists in evaluating the effectiveness of treatments and adjusting interventions accordingly.
Behavior and activity monitoring	Monitors activity levels, locomotion patterns, and behavioral changes (e.g., tail biting, lameness).	Identifies signs of stress, aggression, or health-related issues, improving welfare and reducing injury risks.
Body weight & condition monitoring	Estimates body weight, fat distribution, and overall condition by analyzing body size, shape, and dimensions.	Reduces the need for manual weighing, allows real-time tracking of growth and ensure optimal feeding strategies.
