Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems [PDF]
Appl Plant SciAbstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...
