◆ prepareForRecognition() [1/2]

cv::Mat Digikam::OpenCVDNNFaceRecognizer::prepareForRecognition ( const cv::Mat & cvinputImage )

static

Returns a cvMat created from the cvinputImage, optimized for recognition

◆ prepareForRecognition() [2/2]

cv::Mat Digikam::OpenCVDNNFaceRecognizer::prepareForRecognition ( QImage & inputImage )

static

Returns a cvMat created from the inputImage, optimized for recognition

◆ recognize() [1/2]

QVector< int > Digikam::OpenCVDNNFaceRecognizer::recognize ( const QList< QImage * > & inputImages )

Try to recognize a list of given images. Returns a list of identity ids. If an identity cannot be recognized, returns -1.

◆ recognize() [2/2]

int Digikam::OpenCVDNNFaceRecognizer::recognize ( QImage * inputImage )

Try to recognize the given image. Returns the identity id. If the identity cannot be recognized, returns -1. TODO: verify workflow to economize this routine
