+# 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`
+
+```c++
+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.
