Earth Observation of Ecological Restoration Effectiveness and Ecosystem Functional Recovery in the South China Karst: From Greenness Monitoring to Functional Verification

Long-term Earth observation has reliably documented vegetation greening, biomass increases, and the mitigation of rocky desertification across the South China karst. However, “greening” alone neither demonstrates an incremental effect of ecological restoration interventions nor s...

Effects of Background Composition on Tobacco-Plant Segmentation Accuracy and Cross-Scene Stability in UAV RGB Imagery of Karst Fields

In karst mountainous tobacco fields, white plastic mulch, bare rock, and weeds are spatially interspersed and can affect semantic segmentation accuracy in UAV RGB imagery. This study constructed seven background-composition scenarios from UAV RGB orthomosaics acquired in Zhenfeng...
