GaiaTransform
extends BaseAlgorithm
in package
GaiaTransform
Inputs:
[pool] pool - aggregated pool of extracted values
Outputs:
[pool] pool - pool resulting from the transformation of the gaia point
Parameters:
history: string gaia2 history filename
Description:
Applies a given Gaia2 transformation history to a given pool. It first converts the pool into a gaia2::Point suitable for the history, applies the history, and converts back the resulting point into an essentia Pool. In particular, it allows classification.
Note that in order to enable this algorithm it is necessary to install Gaia2 library before building Essentia.
