UAV-based weed detection in Chinese cabbage using deep learning
Weeds are unwanted plants on agricultural soil. They always competing for sunlight, nutrient, space and water with economic crops.

| Summary: | Weeds are unwanted plants on agricultural soil. They always competing for sunlight, nutrient, space and water with economic crops. Uncontrolled weed growth can cause both significant economic and ecological loss. Hence, weeds should be efficiently differentiated from the crops for the smart spraying solution. In this study, the Convolutional Neural Network (CNN) was used to perform weed detection amongst the commercial crop of Chinese cabbage, using the acquired images by Unmanned Aerial Vehicles. The acquired images were preprocessed and subsequently segmented into the crop, soil, and weed classes using the Simple Linear Iterativ Clustering Superpixel algorithm. The segmented images were then used to construct the CNN-based classifier. The Random Forest (RF) was applied to compare with the performance of CNN. The results showed that the CNN achieved a higher overall accuracy of 92.41% than the 86.18% attained by RF. |
