删除图像的特定部分以外的所有部分

Question

我正在使用 Python 人脸识别库来检测图像中的人脸，它会返回图像中人脸的坐标。我想删除除人脸识别函数返回的坐标外的所有坐标

import face_recognition

image1 = face_recognition.load_image_file("image extract/image.jpg")
face_locations = face_recognition.face_locations(image1)
print(face_locations)

感谢@Mark Setchell 和@Bohdan 的帮助

    count2=0
    for file in image_folder:
        loc=f"image extract/frame{count2}.jpg"
        image1 = face_recognition.load_image_file("image extract/"+file)
        face_locations = face_recognition.face_locations(image1)
        width, height =0,0
        for face_location in face_locations:
            top, right, bottom, left = face_location
            face_image = image1[top+20:bottom+20, left+20:right+20]
            pil_image = Image2.fromarray(face_image)
            if (pil_image.size[0]*pil_image.size[1]>width*height):
                width, height = pil_image.size
                pil_image.save(loc)
