python - 麻烦与代码-> Python识别报纸上的面孔

Question

我的任务是遍历包含一些图像的zip文件，每个图像都是报纸的一页，目标是在页面中搜索单词并显示该页面中识别出的所有面孔。

我将数据存储在字典中，其中的键是图像文件的名称，值是，首先是pytesseract生成的文本，其次是该图像的ZipInfo对象。

生成字典的函数工作正常，因为它生成了我想要的东西，但是问题出在其他两个函数中，wordCheck()和detectFaces()是因为返回了一个空列表

这是代码:

def getDict(zippedFile):
    '''
    This function gets a .zip file containing images and returns a dictionary whose keys are the image names
    and the values are the images text content.
    '''
    j = 0
    i = 0
    dic = {}
    contents = []
    imageObject = []
    with zipfile.ZipFile(zippedFile) as file:
        for single_info in file.infolist():
            imageObject.append(single_info)
            with file.open(single_info) as imageInfo:
                img = Image.open(imageInfo)
                text = pytesseract.image_to_string(img)
                contents.append(text)
    for name in file.namelist():
        dic[name] = [contents[j], imageObject[j]]
        j += 1

    return dic

def detectFaces(imageName, dic):
    '''
    This function gets and image name, that is in a .zip file and returns a list containing bounding boxes for
    faces detected on the given image.
   '''
    boundingBoxes = []
    with zipfile.ZipFile('readonly/small_img.zip') as file:
        imageInfo = dic[imageName][1]
        PILImage = Image.open(imageInfo)
        display(PILImage)
        img = cv.imread(PILImage)
        gray = cv.cvtColor(img, cv.COLOR_BGR2GRAY)
        print(gray)
        faceBoxes = face_cascade.detectMultiScale(gray)

    for item in faceBoxes:
        print(item)
        boundingBoxes.append(item[0])

    return boundingBoxes

def checkWord(word, dic):
    '''

    '''
    bBoxes = []
    for key in dic:
        if word in dic[key]:
            print('Results found in {}'.format(key))
            bBoxes.append(detectFaces(key, dic))
    return bBoxes 


dictera = getDict('readonly/small_img.zip')
result = checkWord('Senator', dictera)
print(result)

我是编程方面的新手，所以如果我犯了一个愚蠢的错误，请原谅我!
我不知道下一步该怎么做，你们对发生的事情有头绪吗？

还有其他一些问题，并且已经解决了，但弄清楚我要返回的列表从未提及。杜尔!
