Real-World Impact: Enhancing Agricultural Inspection
The UWGC framework provides a practical solution to the longstanding challenge of insufficient labeled data in agriculture. By leveraging multimodal knowledge, it significantly improves the accuracy of unsound wheat grain classification, even with limited samples. This advancement is critical for smart agriculture and ensures food quality assurance, enabling more efficient and reliable grain inspection previously unattainable with conventional methods. For instance, in real-world scenarios, quick and accurate identification of moldy or pest-damaged grains prevents spoilage and maintains crop value, leading to reduced waste and improved food security.
