PCAProject Method (InputArray, OutputArray)

public void Project(
	InputArray vec,
	OutputArray result
)

Public Sub Project ( 
	vec As InputArray,
	result As OutputArray
)

public:
void Project(
	InputArray^ vec, 
	OutputArray^ result
)

member Project : 
        vec : InputArray * 
        result : OutputArray -> unit 

Parameters

vec

Type: OpenCvSharpInputArray
input vector(s); must have the same dimensionality and the same layout as the input data used at PCA phase, that is, if DATA_AS_ROW are specified, then `vec.cols==data.cols` (vector dimensionality) and `vec.rows` is the number of vectors to project, and the same is true for the PCA::DATA_AS_COL case.

result

Type: OpenCvSharpOutputArray
output vectors; in case of PCA::DATA_AS_COL, the output matrix has as many columns as the number of input vectors, this means that `result.cols==vec.cols` and the number of rows match the number of principal components (for example, `maxComponents` parameter passed to the constructor).
