Summary
This study introduces a novel two-phase cross-modal model for accurate crop pest identification, overcoming challenges posed by similar pest characteristics and complex field environments. The model significantly improves identification accuracy in real-world agricultural settings.
Area of Science:
- Agricultural Science
- Computer Vision
- Machine Learning
Background:
- Crop pests and diseases pose significant agricultural challenges.
- Identifying pests is difficult due to similar characteristics and complex field environments.
- Conventional single-modal approaches struggle with dynamic surroundings.
Purpose of the Study:
- To develop an advanced cross-modal model for accurate crop pest identification.
- To address limitations of existing methods in complex agricultural settings.
- To enhance the detection of crop pests and diseases.
Main Methods:
- A two-phase cross-modal model was developed for pest identification.
- Phase one used coarse- and fine-grained cross-modal matching on image-text pairs.
- Phase two employed a 'point-to-area' module for key feature super-localization.
Main Results:
- The model achieved improved classification accuracy compared to previous cross-modal models (11.68%, 4.26%, 5.90% increases).
- Validation on IP102 and Li and Xie datasets confirmed effectiveness.
- Experimental results demonstrate suitability for complex environments.
Conclusions:
- The proposed model effectively identifies crop pests in challenging real-world conditions.
- It offers a significant advancement over existing cross-modal identification techniques.
- The model is suitable for practical crop pest and disease monitoring and detection.
