Почему я не могу распознать простой альфа-текст из изображений, используя python,pytesseract,cv2

Question

Я пытаюсь определить текст на кнопках и меню, чтобы убедиться, что они правильно идентифицированы, прежде чем нажимать их. Любая помощь будет принята с благодарностью.

Я пытался изменить цветовые шкалы, изменяя размеры и улучшая изображения, но ничто не может определить то, что мне кажется простым текстом. Я приложу некоторые изображения и код, который был ближе всего. Я пытался использовать следующие сайты и помогает, но пока ничего:

" https://medium.freecodecamp.org/getting-started-with-tesseract-part-ii-f7f9a0899b3f" или " использовать pytesseract для распознавания текста из изображения" или " https://www.pyimagesearch.com/2018/08/20/opencv-text-detection-east-text-detector/"

def I_get_Image_and_Extract_Data(self,image):
        #Use an Image to find it on a screen then check the matched image has the correct text before clicking.
        import PIL
        from PIL import Image, ImageEnhance, ImageFilter
        import pytesseract
        from pytesseract import image_to_string

        ratio = Decimal(4)
        cvimg = cv2.imread(image)
        cvimg2 = cv2.resize(cvimg, None, fx = ratio, fy = ratio, interpolation = cv2.INTER_CUBIC)  # Resize image per calculation above, Also tried different rezizing methods.

        cv2.imwrite("c:\\Temp\\cvtest.png",cvimg2)

        img = Image.open("c:\\Temp\\cvtest.png")
        img = img.convert('L')

        #img = img.filter(ImageFilter.MedianFilter())    ##This completely breaks any recognition
        enhancer = ImageEnhance.Contrast(img)
        img = enhancer.enhance(10)

        img2 = PIL.ImageOps.crop(img,4*ratio)

        #img2 = img2.convert('1')               ##This completely breaks any recognition
        img2.save("c:\\Temp\\test.png")         ##Save a copy just to see what it looks like
        text = image_to_string(Image.open("c:\\Temp\\test.png"),config='-c tessedit_char_whitelist=0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ --psm 6 --oem 1',lang='eng') ##--psm 6,7,9,10 get closest for different images.
        print("Text Found in Image is: '" + text + "'")

Любая помощь, чтобы получить последовательно извлеченный набор текста: все изображения можно найти здесь: https://imgur.com/gallery/pwOz67v
