TABLE II.

Features and Their Computational Complexities for GeoIRIS. Spectral and Texture Feature Sets Are Computed in Three Sets: Panchromatic, Visible Spectrum (RGB), And Near-Infrared (NIR). Aggregate DMP Features Are From Vegetative and Nonvegetative Feature Sets

Feature	Dimension	Complexity
Spectral	8 each	O(H * W)
Texture	21 each	O(H * W + B²)
Linear	37	O(H * W * D * L)
Aggregate DMP	26 each	O(H * W * S * U)
Object Spectral	5	O(N)
Object Shape	32×32	O(N²)
Multi-Object Spatial Relationship	41	O(H * W + N * A)
