Convert Reflectance to Absorbance

Computes A(lambda) = -log10(R(lambda)). Values of R at or below zero are clamped to floor before log transformation.

Usage

hs_absorbance(cube, floor = 1e-06)

Arguments

cube

An hsi_cube object with reflectance values.

floor

Numeric. Minimum reflectance value to prevent log(0). Default 1e-6.

Value

An hsi_cube object with absorbance values.

Examples

cube <- hs_example_cube()
abs_cube <- hs_absorbance(cube)
