Computes the vitual dimensionality (VD) measure for an HSI image for specified false alarm rates.
Computes the vitual dimensionality (VD) measure for an HSI image for specified false alarm rates. When no false alarm rate(s) is specificied, the following vector is used: 1e-3, 1e-4, 1e-5. This metric is used to estimate the number of materials in an HSI scene.
