FisherFaceRecognizerCreate Method

Training and prediction must be done on grayscale images, use cvtColor to convert between the color spaces. - **THE FISHERFACES METHOD MAKES THE ASSUMPTION, THAT THE TRAINING AND TEST IMAGES ARE OF EQUAL SIZE. ** (caps-lock, because I got so many mails asking for this). You have to make sure your input data has the correct shape, else a meaningful exception is thrown.Use resize to resize the images. - This model does not support updating.

Namespace:  OpenCvSharp.Face
Assembly:  OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
Syntax
public static FisherFaceRecognizer Create(
	int numComponents = 0,
	double threshold = 1.79769313486232E+308
)

Parameters

numComponents (Optional)
Type: SystemInt32
The number of components (read: Fisherfaces) kept for this Linear Discriminant Analysis with the Fisherfaces criterion. It's useful to keep all components, that means the number of your classes c (read: subjects, persons you want to recognize). If you leave this at the default (0) or set it to a value less-equal 0 or greater (c-1), it will be set to the correct number (c-1) automatically.
threshold (Optional)
Type: SystemDouble
The threshold applied in the prediction. If the distance to the nearest neighbor is larger than the threshold, this method returns -1.

Return Value

Type: FisherFaceRecognizer
