C++ (Cpp) queryA Examples

Example #1

File: face_recognition.cpp Project: Alegzandra/openbr

int main(int argc, char *argv[])
{
    br::Context::initialize(argc, argv);

    // Retrieve classes for enrolling and comparing templates using the FaceRecognition algorithm
    QSharedPointer<br::Transform> transform = br::Transform::fromAlgorithm("FaceRecognition");
    QSharedPointer<br::Distance> distance = br::Distance::fromAlgorithm("FaceRecognition");

    // Initialize templates
    br::Template queryA("../data/MEDS/img/S354-01-t10_01.jpg");

    br::Template target("../data/MEDS/img/S354-02-t10_01.jpg");

    // Enroll templates
    queryA >> *transform;
    queryB >> *transform;
    target >> *transform;

    printTemplate(queryA);

    printTemplate(target);

    // Compare templates
    float comparisonA = distance->compare(target, queryA);
    float comparisonB = distance->compare(target, queryB);

    // Scores range from 0 to 1 and represent match probability
    printf("Genuine match score: %.3f\n", comparisonA);
    printf("Impostor match score: %.3f\n", comparisonB);
