FUNCTIONface_getFacesHAAR

RETURN TYPEboolean

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Default face detector This function is mainly utilized by the implementation of a Facemark Algorithm. End users are advised to use function Facemark::getFaces which can be manually defined and circumvented to the algorithm by Facemark::setFaceDetector.

std::vector<cv::Rect> faces;
CParams params("haarcascade_frontalface_alt.xml");
cv::face::getFaces(frame, faces, &params);
for(int j=0;j<faces.size();j++){
    cv::rectangle(frame, faces[j], cv::Scalar(255,0,255));
}
cv::imshow("detection", frame);

face_getFacesHAAR(image: Mat, faces: Mat, face_cascade_name: EmbindString): boolean;

image: The input image to be processed.
faces: Output destination, filled by the native operation. Output of the function which represent region of interest of the detected faces. Each face is stored in cv::Rect container.
face_cascade_name: face cascade name argument (EmbindString).

Returns

The boolean result.
