Particularly, they can’t segment green crops from complex soil backgrounds, such as with high light or deep shadow areas in crop leaves. To address current defic

Invariant Subspaces, transformation” and “bounded linear transformation” are synonyms (a transformation . of . into . is . if there exists a constant .≥ 0 such that ||.|| ≤ .||.|| for every . in .). We shall use the same notation for the norms on ., . and also for the induced (uniform) norm on .[.,.]: . for every . ∈ .
