knn_mean: Multivariate local means

In benja0x40/QuickShift: QuickShift

Description

compute k-nearest neighbor (knn) centroids (i.e. mean vectors).

Usage

knn_mean(x, k, xref = NULL, nn_alg = "kd_tree")

Arguments

x	numeric matrix representing multivariate data where rows = observations and columns = measurement conditions (query data).
k	number of nearest neighbors which has equivalent effects as the usual bandwidth or smoothing parameters (larger k => smoother results).
xref	numeric matrix representing multivariate data where rows = observations and columns = measurement conditions (optional reference data).
nn_alg	nearest neighbor searching algorithm (default = "kd_tree"). See get.knn for further explanations.

Value

knn_mean returns a matrix of knn centroids.
