Question

我正在尝试识别按钮和菜单上的文本，以确保它们是正确识别的文本，然后再单击它们。任何帮助将不胜感激。

我尝试过修改色阶，调整图像大小和增强图像，但是似乎没有什么能够识别出看起来像是简单文本的内容。我将附加一些图像和最接近的代码。我尝试过使用以下网站，但到目前为止没有帮助：

“ https://medium.freecodecamp.org/getting-started-with-tesseract-part-ii-f7f9a0899b3f”或 “ use pytesseract to recognize text from image”或 “ 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 + "'")

获得一致提取的文本集的任何帮助：所有图片都可以在这里找到：http://imgur.com/gallery/pwOz67v

我可以做到的最接近结果：

为什么我无法使用python，pytesseract，cv2从图像中识别简单的Alpha文本
