如何使用cv2.putText在检测到的面部上方显示名称？

Question

enter image description here我在基于图像的面部识别应用程序中使用了dlib。如何使用cv2.putText在检测到的面孔上方写下姓名？

for ( k, face ) in enumerate( face_image ):  

    faceBlob = cv2.dnn.blobFromImage(face, 1.0 / 255,
    (96, 96), (0, 0, 0), swapRB=True, crop=False)
    embedder.setInput(faceBlob)
    vec = embedder.forward()

    # perform classification to recognize the face
    preds = recognizer.predict_proba(vec)[0]
    j = np.argmax(preds)
    proba = preds[j]
    name = le.classes_[j]

Answer 1

尝试使用这些值。

    font = cv2.FONT_HERSHEY_SIMPLEX 
    org = (x, y) 
    fontScale = 1 #(try differnt values)
    color = (0, 0, 0) 
    thickness = 2 #(try differnt values)
    image = cv2.putText(img, "TEXT", org, font,  
                       fontScale, color, thickness, cv2.LINE_AA)
