如何保存裁剪后的图像？

Question

我想将裁剪后的图像保存在同名的新文件夹中。 我试过这段代码，代码提取人脸，但文件夹中没有保存的图像。 谢谢你。

image_path = glob.glob('/content/drive/MyDrive/ID01/')

def extract_face_from_image(image_path, required_size=(224, 224)):
  face_images = []
  for filename in os.listdir(image_path):
    for img in filename:
        image = cv2.imread(os.path.join(image_path, filename))
        face_images.append(image)
        detector = MTCNN()
        faces = detector.detect_faces(image)
  for face in faces:
# extract the bounding box from the requested face
    x1, y1, width, height = face['box']
    x2, y2 = x1 + width, y1 + height

    # extract the face
    face_boundary = image[y1:y2, x1:x2]

    # resize pixels to the model size
    face_image = Image.fromarray(face_boundary)
    face_image = face_image.resize(required_size)
    face_array = asarray(face_image)
    face_images.append(face_array)
    cv2.imwrite(os.path.join('/content/drive/MyDrive/out/'),str(face), extracted_face)
extracted_face = extract_face_from_image('/content/drive/MyDrive/ID01/')
# cv2.imwrite(os.path.join('/content/drive/MyDrive/out'),str(face), extracted_face)

Answer 1

您的os.path.join调用中有错字。 您不小心在'/content/drive/MyDrive/out/'后面加上了右括号。 此外，您在 function 中已经extracted_face了_face ，您将在其中extracted_face _face 。 我认为您打算改用face_image 。 该行可能应该是：

cv2.imwrite(os.path.join('/content/drive/MyDrive/out/', str(face)), face_image)

最后，不要忘记从extract_face_from_image()返回一些东西，否则extracted_face将只是None 。
