示例1: predict
void FisherFaceRecognizer::predict(cv::InputArray _src, cv::Ptr<cv::face::PredictCollector> collector) const
{
qCWarning(DIGIKAM_FACESENGINE_LOG) << "Predicting face image using fisherfaces";
if (m_projections.empty())
{
// throw error if no data (or simply return -1?)
String error_message = "This Fisherfaces model is not computed yet. Did you call the train method?";
CV_Error(CV_StsBadArg, error_message);
}
Mat src = _src.getMat();//254*254
//make sure the size of input image is the same as training image
if (m_src.size() >= 1 && (src.rows != m_src[0].rows || src.cols != m_src[0].cols))
{
//resize(src, src, Size(m_src[0].rows, m_src[0].cols), (0, 0), (0, 0), INTER_LINEAR);
resize(src, src, Size(m_src[0].rows, m_src[0].cols));
}
collector->init(0);//here need to confirm
Mat q = LDA::subspaceProject(m_eigenvectors, m_mean, src.reshape(1, 1));
//find nearest neighbor
for (size_t sampleIdx = 0 ; sampleIdx < m_projections.size() ; sampleIdx++)

int label = m_labels.at<int>((int) sampleIdx);
