Classes

class dip::StatisticsAccumulator: StatisticsAccumulator computes population statistics by accumulating the first four central moments.
class dip::VarianceAccumulator: VarianceAccumulator computes mean and standard deviation by accumulating the first two central moments.
class dip::FastVarianceAccumulator: FastVarianceAccumulator computes mean and standard deviation by accumulating the sum of sample values and the sum of the square of sample values.
class dip::CovarianceAccumulator: CovarianceAccumulator computes covariance and correlation of pairs of samples by accumulating the first two central moments and cross-moments.
class dip::DirectionalStatisticsAccumulator: DirectionalStatisticsAccumulator computes directional mean and standard deviation by accumulating a unit vector with the input value as angle.
class dip::MinMaxAccumulator: MinMaxAccumulator computes minimum and maximum values of a sequence of values.
class dip::MomentAccumulator: MomentAccumulator accumulates the zeroth order moment, the first order normalized moments, and the second order normalized central moments, in N dimensions.
