costWd

Description

Objective function to minimize when using GMMs

Usage

costWd(Tr, X, Y, CX, CY, w1 = NULL, w2 = NULL, S = NULL)

Arguments

Tr	Transformation vector as translation vector + rotation (angle in 2d, quaternion in 3d))
X	matrix of means of first GMM (i.e. reference point set)
Y	matrix of means of second GMM (i.e. moving point set)
CX	array of covariance matrices of first GMM such that X[i,] has covariance matrix CX[,,i]
CY	array of covariance matrices of second GMM such that Y[i,] has covariance matrix CY[,,i]
w1	(optional) vector of mixture weights of first GMM.
w2	(optional) vector of mixture weights of second GMM.
S	(optional) array of pre-computed sqrtm(sqrtm(CX[,,i]) %*% CY[,,j] %*% sqrtm(CX[,,i]))
