之前发的博客和网上流传的代码严格来说都只算得上是人脸检测，不能区别人脸，今天来说说真的人脸识别篇幅所限，就举两张人脸的例子了，本程序需要安装face_recognition

下面是全部源代码：

import face_recognition from PIL import Image, ImageDraw # This is an example of running face recognition on a single image # and drawing a box around each person that was identified. # Load a sample picture and learn how to recognize it. obama_image = face_recognition.load_image_file("C:/Users/CJK/Desktop/1.jpg") obama_face_encoding = face_recognition.face_encodings(obama_image)[0] # Load a second sample picture and learn how to recognize it. biden_image = face_recognition.load_image_file("C:/Users/CJK/Desktop/2.jpg") biden_face_encoding = face_recognition.face_encodings(biden_image)[0] # Create arrays of known face encodings and their names known_face_encodings = [ obama_face_encoding, biden_face_encoding ] known_face_names = [ "obama", "biden" ] # Load an image with an unknown face unknown_image = face_recognition.load_image_file("C:/Users/CJK/Desktop/3.jpg") # Find all the faces and face encodings in the unknown image face_locations = face_recognition.face_locations(unknown_image) face_encodings = face_recognition.face_encodings(unknown_image, face_locations) # Convert the image to a PIL-format image so that we can draw on top of it with the Pillow library # See http://pillow.readthedocs.io/ for more about PIL/Pillow pil_image = Image.fromarray(unknown_image) # Create a Pillow ImageDraw Draw instance to draw with draw = ImageDraw.Draw(pil_image) # Loop through each face found in the unknown image for (top, right, bottom, left), face_encoding in zip(face_locations, face_encodings): # See if the face is a match for the known face(s) matches = face_recognition.compare_faces(known_face_encodings, face_encoding) name = "Unknown" # If a match was found in known_face_encodings, just use the first one. if True in matches: first_match_index = matches.index(True) name = known_face_names[first_match_index] # Draw a box around the face using the Pillow module draw.rectangle(((left, top), (right, bottom)), outline=(0, 0, 255)) # Draw a label with a name below the face text_width, text_height = draw.textsize(name) draw.rectangle(((left, bottom - text_height - 10), (right, bottom)), fill=(0, 0, 255), outline=(0, 0, 255)) draw.text((left + 6, bottom - text_height - 5), name, fill=(255, 255, 255, 255)) # Remove the drawing library from memory as per the Pillow docs del draw # Display the resulting image pil_image.show() # You can also save a copy of the new image to disk if you want by uncommenting this line # pil_image.save("image_with_boxes.jpg")
