چکیده
The excessive use of agricultural pesticides and inputs has caused severe environmental damage to agricultural ecosystems. By applying digital agriculture and variable rate application systems, various sections of a farm can be managed with varying levels of pesticides and inputs, which is beneficial both in terms of production costs and environmental issues. In this study, a weed and saffron plant detection model was designed and evaluated to develop a selective weed control system in saffron fields. The proposed weed detection model is based on the Yolov5 object detection model. Several CBS and C3 modules in the Yolov5s model were replaced with Ghost Bottleneck and C3Ghost modules, respectively. This was done to reduce the number of model parameters and make the network lighter, which increases the speed of image processing during model training and inference. Furthermore, to improve the detection accuracy of the proposed model, a coordinate attention (CoordAtt) layer was used. The results showed that the number of parameters in the proposed model was reduced by 47% compared to the corresponding model in terms of network width and depth coefficients in Yolov5 versions. Meanwhile, among the six trained models, the modified Yolov5s model demonstrated the best performance, achieving accuracy and recall values equal to 81% and 67%, respectively. The detection accuracy of the proposed model was 3.93% higher than that of the best-performing Yolov5 algorithm. Due to the lightweight nature of the proposed algorithm, it can be used for real-time weed detection in agricultural fields to develop selective control systems.
