I pulled this project from here, (github : /freesouls/face-alignment-at-3000fps), and am trying to optimize the data loading of the program. I can't quite understand these few lines, however.
// Face alignment
cv::Mat_<uchar> tmp;
gray.copyTo(tmp);
cv::Mat_<double> current_shape = ReProjection(cas_load.params_.mean_shape_, bbox);
// |current_shape| will be overwritten during the Predict call.
cv::Mat_<double> res = cas_load.Predict(tmp, current_shape, bbox);
for (int i = 0; i < res.rows; i++){
cv::circle(frame, cv::Point2f(res(i, 0), res(i, 1)), 2, Scalar( 255, 255, 255 ));
}
Nor could I find any reference to 'ReProjection' in the docuemntation, or CascadeRegressor... Other relevant lines:
CascadeRegressor cas_load;
Mat frame, gray;
Where might I find the appropriate documentation?
