Flandmark 是一个开源实现面部地标探测器。提供 MATLAB 接口。

C++ 示例代码：

#include "flandmark_detector.h"

int main(int argc, char * argv[])
{
  // load flandmark model structure and initialize
  FLANDMARK_Model * model = flandmark_init("flandmark_model.dat");

  // load input image
  IplImage *img = cvLoadImage("photo.jpg");

  // convert image to grayscale
  IplImage *img_grayscale = cvCreateImage(cvSize(img->width, img->height), IPL_DEPTH_8U, 1);
  cvCvtColor(img, img_grayscale, CV_BGR2GRAY);

  // bbox with detected face (format: top_left_col top_left_row bottom_right_col bottom_right_row)
  int bbox[] = {72, 72, 183, 183};

  // detect facial landmarks (output are x, y coordinates of detected landmarks)
  float * landmarks = (float*)malloc(2*model->data.options.M*sizeof(float));
  flandmark_detect(img_grayscale, bbox, model, landmarks);
}
