将 PIL 的输出（多个文件）保存到目录

Question

我正在做一个基本项目，它需要我拍摄图像并将面部（仅）与该图像分开，并将它们输出到一个单独的文件夹。到目前为止，我已经编写了下面的代码（编码新手和 Python）。这段代码的唯一问题是当我知道有多张脸时它只保存一张图片。如果我用注释部分 pil_image.show() 替换最后一行，那么它会通过为每个人打开一个单独的文件来向我显示所有面孔，但不会在任何地方保存输出。

我需要有关指向软件的帮助，以便它将所有输出保存在一个目录中。

from PIL import Image
import face_recognition

path = r"C:\Users\Julio\Desktop\Output\new"
image = face_recognition.load_image_file("MultiPeople/twopeople.jpeg")
count = 0

face_locations = face_recognition.face_locations(image)

print("I found {} face(s) in this photograph.".format(len(face_locations)))

for face_location in face_locations:
    top, right, bottom, left = face_location
    print("I found a face in image location Top: {}, Left: {}, Bottom: {}, Right: {}".format(top, left, bottom, right))

    face_image = image[top:bottom, left:right]
    pil_image = Image.fromarray(face_image)
    pil_image.save(str(path) + ".jpg")

    #pil_image.show()

Answer 1

错误在第 .. pil_image.save(str(path) + ".jpg") 行，因为所有文件都写在循环中的同一文件路径上。

你可以试试这个。

face_counter = 0
for face_location in face_locations:
    top, right, bottom, left = face_location
    print("I found a face in image location Top: {}, Left: {}, Bottom: {}, Right: {}".format(top, left, bottom, right))

    face_image = image[top:bottom, left:right]
    pil_image = Image.fromarray(face_image)
    pil_image.save(str(path) + str(face_counter) + ".jpg")
    face_counter += 1
