Detecting Pine Trees Damaged by Wilt Disease Using Deep Learning Techniques Applied to Multi-Spectral Images

چکیده
Pine wilt disease (PWD) is responsible for significant damage to East Asia’s pine forests, including those in Korea, Japan, and China. Preventing the spread of requires early detection removal damaged trees. This paper proposes a method detecting disease-damaged pines using ortho-images corrected from 5-band multi-spectral images captured by unmanned aviation vehicles. The proposed relies on ResNet18 backbone network connected modified DenseNet module, classifies multispectral (RGB, NIR, Red_Edge) ortho-image patches, visualizes results as heat map. patch-based classifier was retrained with hard negative examples, after which it achieved 98.66% accuracy, an improvement over 96.0% accuracy associated same applied RGB images. resulting map reflects approximate distribution, movement disease. Disease locations are also predicted local maximums When distance between ground truth location less than visible distance, e.g. about 5m, counted correct detection. consists generation followed localization achieves Recall 93.39%, Precision 88.26%, F1-score 90.75%.

Detection of the Pine Trees Damaged by Pine Wilt Disease Using High Spatial Remote Sensing Data
Since 1988 pine wilt disease has spread over rapidly in Korea. It is not easy to detect the damaged pine trees by pine wilt disease from conventional remote sensing skills. Thus, many possibilities were investigated to detect the damaged pines using various kinds of remote sensing data including high spatial resolution satellite image of 2000/2003 IKONOS and 2005 QuickBird, aerial photos, and d...

متن کاملDetecting Overlapping Communities in Social Networks using Deep Learning
In network analysis, a community is typically considered of as a group of nodes with a great density of edges among themselves and a low density of edges relative to other network parts. Detecting a community structure is important in any network analysis task, especially for revealing patterns between specified nodes. There is a variety of approaches presented in the literature for overlapping...
متن کاملPine wilt disease – a threat to pine forest in Europe
Pine wilt disease caused by pine wood nematodes is endemic to North America. Pine wood nematodes have already spread to East Asia, including China, Taiwan and Korea in addition to Japan. The pine wood nematode, Bursaphelenchus xylophilus, was discovered in Portuguese pine forests in 1999. If it were to become established in the pine forests in Europe, it could become one of the most serious thr...
