[OpenCV] detectMultiScale: output detection score

OpenCV provides quite decent implementation of the Viola-Jones Face detector. A quick example looks like this (OpenCV 2.4.5 tested): // File: main.cc #include using namespace cv; int main(int argc, char **argv) { CascadeClassifier cascade; const float scale_factor(1.2f); const int min_neighbors(3); if (cascade.load(“./lbpcascade_frontalface.xml”)) { for (int i = 1; i < argc; i++) { Mat img […]
