frechet_func(bary, data)
Arguments
bary
An object representing a measure, for which the Frechet value should be computed. Should be one of the following:
A matrix, representing an image; A path to a file containing an image;
A wpp-object;
A pp-object;
A list containing an entry named 'positions' with the support of the measure and an entry named 'weights' containing the weights of the support points;
A list containing en entry named 'positions“ specifying the support of a measure with uniform weights.
data
A list of objects which should be compared to bary. Each element should be one of the following:
A matrix, representing an image; A path to a file containing an image;
A wpp-object;
A pp-object;
A list containing an entry named 'positions' with the support of the measure and an entry named 'weights' containing the weights of the support points;
A list containing en entry named 'positions“ specifying the support of a measure with uniform weights.
Value
A real number specifying the Frechet value of the input object for the given dataset.
