gemm()

void DirectGraphicalModels::parallel::gemm ( const Mat &  A, const Mat &  B, float  alpha, const Mat &  C, float  beta, Mat &  res  )

inline

Fast generalized matrix multiplication.

Parameters

A	first multiplied input matrix that should have CV_32FC1, CV_64FC1, CV_32FC2, or CV_64FC2 type.
B	second multiplied input matrix of the same type as src1.
alpha	weight of the matrix product.
C	third optional delta matrix added to the matrix product; it should have the same type as src1 and src2.
beta	weight of src3.
res	output matrix; it has the proper size and the same type as input matrices.

shuffleRows()

void DirectGraphicalModels::parallel::shuffleRows ( Mat &  m )

inline

Randomly shuffles the rows of the input matrix.

This function supports PPL. When using PPL, the result of this function is biased.

Parameters

[in,out]

m

The input/output data, which rows should be shffled.

Todo:

Eliminate the bias, caused by parallel processing.

sortRows() [1/2]

template<typename T >

void DirectGraphicalModels::parallel::sortRows ( Mat &  m, int  x  )

inline

Sorts the rows of the input matrix by the given dimension.

The result of the sorting may is expressed as: \( m_{x,y} < m_{x,y+1}, \forall y \).

This function supports PPL.

Template Parameters

T	The type of elements in matrix.

Parameters

[in,out]	m	The input/output data, which rows should be sorted.
	x	The dimension along which the matrix is sorted.
