    Thank you for all your good tutorials! Could you make a video on natural scene text detection using opencv and EAST one day??

    Hi - thanks for the excellent tutorial. This really helps a lot. While running your code on the image that I have extracted from my PDF document, instead of printing the text in the image file, it is spitting out some texts as below :
    code :
    image =cv2.imread("page-12.png")
    cv2.waitKey(0)
    Output :
    -1
    code :
    text = pytesseract.image_to_string(image)
    Print(text)
    output :
    DF Metadata Extraction with Python

    file = PyPDr2
    xnp = pdf_file.getimphetadatal
    dict = 0
    4 in mp methods

    xnp_dict (i)
    pp.pprint xmp dict)

    anytestringobject if pyPDr2 is unable to decode the string (Fenniak, 2016b). Putting
    these two methods together yields a custom function that can be used to extract document
    information dictionary metadata from PDF files (sce

    igure 9). The resulting

    DocumentInformation object which generated by the custom get_doc_info()
    function contains a dictionary with five key:value pairs (see Figure 10). This extracted data
    ‘matches the raw metadata located in the Document Information Dictionary abject located

    at 208 0 obj inthe file (see Figure 3).

      Hi...I ran your code again and it is working. So you may ignore the above comment. The problem is my file has a dark background and so with the values that you have shown for adjusted threshold do not seem to be converting the background to white and the print(text) is still not showing the text embedded within the picture.
      My picture file is PNG - will that require a different adjustment to your code and the threshold values?
      Thanks - really appreciate

    One issue with the Chinese text is that the first two characters are in traditional Chinese and the second two characters are the simplified. So the first time you ran it and it gave you 汉语,汉语 was correct as it converted the traditional into simplified because you used chi_sim.

    Wow very good, but the problem is "If the text is very clear and crisp its is showing output correctly", But I want to know if the image has multiple data not only text for example "bills, taken calendar photo or any kind of images", How to print the string from that, I tried my self it's not printing anything, Any idea for this?

      it can detect digits since date is mostly in digits i think it will work well.

      First you need to cut that region. Check my youtube videos "Crop images" and you'll know hot to d that.
      once you did cut the portion, you can parse that one to the OCR
