EBI Algorithm Specification

EBI

The EBI operator algorithm computes the Enhanced Bloom Index from a given product.

The EBI results from the following equation:

EBI = (R + G + B) / ((G / B) * (R - B + epsilon))

, where:

The bands are:

- B is the Blue band
- G is the Green band
- R is the Red band


and the coefficients are:

- l is the Canopy background adjustment coefficient
- epsilon is the Epsilon coefficient parameter coefficient

EBI-Flags

Also the processor computes an additional flags band called 'ebi_flags' with the following bit coding:

Bit Position Description
Bit 0 The computed value for EBI is NAN or is Infinite
Bit 1 The computed value for EBI is less than -1 (minus one)
Bit 2 The computed value for EBI is greater than 1 (one)
