Face Detection Results

The FaceDetectionResult function is defined in csrcs/fastdeploy/vision/common/result.h , indicating the object's frame, face landmarks , target confidence and the number of landmarks for each face detected.

C++ Definition

fastdeploy::vision::FaceDetectionResult

struct FaceDetectionResult {
  std::vector<std::array<float, 4>> boxes;
  std::vector<std::array<float, 2>> landmarks;
  std::vector<float> scores;
  int landmarks_per_face;
  void Clear();
  std::string Str();
};

• boxes: Member variable that indicates the coordinates of all object boxes detected from an image.boxes.size() indicates the number of boxes, and each box is represented by 4 float values in the order xmin, ymin, xmax, ymax, i.e. the top left and bottom right coordinates.
• scores: Member variable that indicates the confidence level of all objects detected from a single image, with the same number of elements as boxes.size().
• landmarks: Member variable that indicates the key points of all faces detected in a single image, with the same number of elements as boxes.size().
• landmarks_per_face: Member variable that indicates the number of key points in each face frame.
• Clear(): Member function that clears the results stored in a struct.
• Str(): Member function that outputs the information in the struct as a string (for Debug).

Python Definition

fastdeploy.vision.FaceDetectionResult

• boxes(list of list(float)): Member variable that indicates the coordinates of all object boxes detected from an image. Boxes are a list, with each element being a 4-length list presented as a box with 4 float values for xmin, ymin, xmax, ymax, i.e. the top left and bottom right coordinates.
• scores(list of float): Member variable that indicates the confidence level of all objects detected from a single image.
• landmarks(list of list(float)): Member variable that indicates the key points of all faces detected in a single image.
• landmarks_per_face(int): Member variable that indicates the number of key points in each face frame.
