Hello

I am trying to use pytessaract for text detection in a GUI Swing java, the probleme is I don't know how to improve the result, and specialy when the font is small, please can i have some advice for that ?

Thanks,

The image seems to open, but then when I run image_to_string, it throws an exception:

>>> i = Image.open('test.png')

I testing pytesseract, some images are recognized but not others.
The images not recognized are photos with text, the error is:

I tested some commands of chcp, i.e:

My actual code is:

print "Running..."
print(pytesseract.image_to_string(Image.open('enc1.tiff'), boxes=False))

Is there any way for pytesseract to continue with recognition regardless of errors?

How to prevent this ?

I have added the code for getting the output in tsv format. Please give me the permission to push code and raise a pull request for the review.
Thanks

When I run print pytesseract.image_to_string(image, boxes=False, config="-psm 0")

I get the processed string of the text in the image. However, psm 0 is supposed to only test the orientation. If you run this via the command line, the output should be like this:

Tesseract Open Source OCR Engine v3.04.00 with Leptonica
Orientation: 2
Orientation in degrees: 180
Orientation confidence: 0.28
Script: 2
Script confidence: 0.04

The code looks like it should be correct, and you have accounted for this, but I do not get the result. I'm not sure what the problem is, I tried to debug it for a few hours. Still trying.

I ran into instances of a UnicodeDecodeError when processing some images, particularly ones where the type isn't very clear.

It seems like what's happening is tesseract's putting in some bytes that python has trouble picking out the codec for. I did a bit of digging around it seems like the standard output from tesseract is encoded in utf-8:

https://code.google.com/p/tesseract-ocr/wiki/FAQ#What_output_formats_can_Tesseract_produce?

Altering the file open command in pytesseract.py to explicitly state the expected encoding prevents the error, but also changes the print behaviour (returns encoded bytes instead of a string):

f = open(output_file_name, encoding='utf-8', errors='replace')

Altering the return command to encode the output to ascii, and then decode it, allows the current output to be maintained (as far as I can see - tested it with a few working images) and also squashes the UnicodeDecodeErrors.

return f.read().strip().encode('ascii', 'replace').decode('ascii', 'replace')

This seems to work.. and seems to allow processing of any image to get some output, however useful it may be.

Thoughts welcome - not sure if it's the best way to go about resolving the errors.

pytesseract.pytesseract.tesseract_cmd = '<full_path_to_your_tesseract_executable>'

Include the above line, if you don't have tesseract executable in your PATH

Example tesseract_cmd: 'C:\Program Files (x86)\Tesseract-OCR\tesseract'

Where should I to download the executable, please? I am working on ubuntu and mac OS

Hi!
When I use the tesseract in my terminal（OS X 10.11.3） like this:

tesseract test.png out

It will raise a warning:Empty page!!.
But when I use pytesseract in my code(Python 2.7.10) like this:

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract

receipt = Image.open('test.png')
receipt.load()
print(pytesseract.image_to_string(receipt))

The output is consist of 2 empty lines.
So, the 'Empty page!!' warning doesn't show in the output.
Thanks.

Running pytesseract on Raspbian, python 2.7, tesseract 4.00 (4.00.00dev-625-g9c2fa0d).

My code is as follows:

ret = image_to_string(im,lang='eng',boxes=False, config="-psm 0")

Error:

Traceback (most recent call last):

If I run code with psm 1 [Recognition with OSD], I receive no errors but the upside down text is simply treated as right-side-up text, producing garbage results. (This was tested on an inverted test.png)

Essentially text recognition works but OSD does not.

I installed OCR from the google page and I have successfully imported the library Pytesseract, but when I tried to compile this code on python and get these errors from Pytesseract.py and subprocess.py.

I went through all the previous Issues regarding this matter and I've updated my tesseract version to 4.0 and have all the trained files available. But, I'm getting this error, what's the issue and how can it be fixed?

Older issue : #32

I even tried this step mentioned in SO answer, but after this, I have the same problem as OP. The error changes to

hi there,

I have a feature request to recognize a bunch of verification codes with Tesseract-ocr, and I used pytesseract.

It works perfectly for an image with only letters. However, if the image consists of both digits and letters, the output always wrong. Is there any solution to increase quality for this scenario? Or can is that possible to involve some supervised process to improve accuracy.

Attachment is a false example for recognization and the output is "N 3U’7V".

Here is the code:

import sys
from pytesseract import image_to_string
from PIL import Image
im = Image.open(sys.argv[1])
im = im.convert('L')

def initTable(threshold=140):
table = []
    for i in range(256):
    if i < threshold:
        table.append(0)
    else:
        table.append(1)

return table

binaryImage = im.point(initTable(), '1')
binaryImage.show()

print(image_to_string(binaryImage, config='-psm 7'))

When using python 3.5 and pillow (the original PIL library is quite old now), I receive an error on this very simple example:

import pytesseract

try:
    import Image
except ImportError:
    from PIL import Image

pytesseract.image_to_string(Image.open('test_image.png'))

The error is:

Traceback (most recent call last):

I have created a seperate custom dictionary and a custom function which works perfect with normal command line tesseract but I want to know how to use the same in the pytesseract package. Because in pytesseract it is not using that function, neither am having any clue of how to provide the function name .

In normal I use:
tesseract test.png myfunc #myfunc being the custom function

How to do the same in pytesseract

Build info: pytesseract v0.17 with tesseract v4.0 built from source, running on Ubuntu 16.04 64-bit

In the function image_to_string there's a comment saying that the method used to remove the alpha channel is kind of a hack, while that method worked pretty well I'd like to propose using an alternative using the convert method built into PIL Image objects . This function is faster than the current implementation, and simplifies the code.

if len(image.split()) == 4:
    # In case we have 4 channels, lets discard the Alpha.
    # Kind of a hack, should fix in the future some time.
    r, g, b, a = image.split()
    image = Image.merge("RGB", (r, g, b))

The time for this current implementation to remove the alpha channel is 0.002046s,
My proposed implementation took around 0.000678s to remove the alpha channel. The code would directly replace the previous block of code:

if len(image.split()) == 4:
    image.convert('RGB')

This is the image both implementation was tested on:

I've submitted this change as PR#80.

Perhaps turning the code into a class, the tesseract path as well as the rest of the configuration options could be passed during initialization.

there happens error when i run the code:

from PIL import Image
import pytesseract

im1_path = r"D:\pictures\8.png"
image = Image.open(im1_path)
captcha_code = pytesseract.image_to_string(image)
print(captcha_code)

Hey guys! I am pretty new at programming Python so take it easy with me please! I have an image provided above and if I use:

print pytesseract.image_to_string(img)

it returns:

Rggimantasih

Which is pretty close but as you can guess not fully accurate.

I tried converting image to black and white/grayscale but that did not help. Image and letters seem pretty clear maybe you can help me out here? Thanks in advance!!

I am using pytesseract in Python3 code:

#!/usr/bin/env python3

from PIL import Image
import pytesseract

file = "file.txt"
text = tess(Image.open(file), lang=eng)

Everythink work fine, but when I wrote first unittest I get following warning:

/usr/lib/python3.4/site-packages/pytesseract/pytesseract.py:161: ResourceWarning: unclosed file <_io.BufferedReader name=4>  config=config)

Version: 0.1.6, unittesting via std unittest module.

	image=Image.open('C:\\Users\\Bobliao\\Desktop\\GetValidateCode.jpg')
	tessdata_dir_config = '--tessdata-dir "E:\\Program Files (x86)\\Tesseract-OCR\\tessdata"'
	b=pytesseract.image_to_string(image,config=tessdata_dir_config)

str b is empty and no errors happen.

below is my sample JPG

pytesseract does not run in python 3 without errors. There are some small issues that need fixing to make things run without errors on python 2 and 3.

In pytesseract.py:

• All print statements need to be inside parentheses.

  print(image_to_string(image))
  

• StringIO needs to be imported from the io module

  from io import StringIO
  

• StringIO direct usage needed
  sys.stderr = StringIO()

• os.tempnam needs to be refactored because it is deprecated. https://docs.python.org/2/library/os.html#os.tempnam. One solution is to replace:

  return os.tempnam(None, 'tess_')
  

  with

  import tempfile
  with tempfile.NamedTemporaryFile() as tf:
      tmpname = 'tess_' + os.path.basename(tf.name)
  return tmpname
  

• file() is deprecated and should to be changed to open():

  f = open(output_file_name)
  

In init.py import needs to be explicit:

  from .pytesseract import image_to_string

With these changes I could run pytesseract on both python 2.7 and python 3.5.

Here is my code.

from PIL import Image
import pytesseract
img = Image.open('/Users/songmingyang/Pictures/ocr-test.png')
pytesseract.image_to_string(img)

Then return an Error.

TypeError: a bytes-like object is required, not 'str'

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files (x86)\Tesseract-OCR'
x = pytesseract.image_to_string(Image.open('cropped.png'))

I can use your config interface to add config=+hocr.txt, and include in that file a command to output hocr, but then the file cleanup process gets buggy because it looks for either .box or .txt, not .html's. the most logical way to fix this would probably be to directly switch "box=true' to something like "output" where output permits either box or hocr/html...

stuck in error.

I think I've installed all the dependencies needed but can't solve this one.

I am using pytesseract on windows 10 x64, and the python is 3.5.2 x64, Tesseract is 4.0 ,the code is as follow:

# -*- coding: utf-8 -*-

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract


print(pytesseract.image_to_string(Image.open('d:/testimages/name.gif'), lang='chi_sim'))

error:

Traceback (most recent call last):
  File "D:/test.py", line 10, in <module>
    print(pytesseract.image_to_string(Image.open('d:/testimages/name.gif'), lang='chi_sim'))

pytesseract.pytesseract.TesseractError: (1, 'Error opening data file \\Program Files (x86)\\Tesseract-OCR\\tessdata/chi_sim.traineddata')

C:\Program Files (x86)\Tesseract-OCR\tessdata,like this:

The usage section says the way to use pytesseract is

print(pytesseract.image_to_string(Image.open('test.png')))

I'm wondering if there is a way to avoid I/O. I am using OpenCV to do some image pre-processing prior to sending images to tesseract. Is there a way I can send the image from OpenCV directly to pytesseract instead of first saving it to a file? Here is what I have to do now

#save image from OpenCV to disk
cv2.imwrite(path_to_image, my_image)
print(pytesseract.image_to_string(Image.open(path_to_image)))

This way I have to first write the image to the disk. I believe this will not be scalable in a distributed architecture because of the I/O involved. Any way to avoid this?

Hi,
I found your project very useful and I like to thank you for your work :)
But after using it in standalone executable on windows, I'd like to suggest small improvement.
Currently (on win 8 and standalone exe) every call to pytesseract make console window to appear for ~1s which is very unpleasant. This small fix resolve this issue for me:

sinfo = subprocess.STARTUPINFO()
sinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE | subprocess.STARTF_USESHOWWINDOW
sinfo.wShowWindow = subprocess.SW_HIDE
proc = subprocess.Popen(command, stderr=subprocess.PIPE, startupinfo=sinfo)

Would you consider adding some setting(or better solution) to allow user to decide, if console should be visible?

This directly from PIL.
I am trying to run this very basic against a single file in the same directory. Won't work.

Python 2.7 Mac OS X.

code:

try:
import Image
except ImportError:
from PIL import Image
import pytesseract
tessdata_dir_config = '--tessdata-dir "<replace_with_your_tessdata_dir_path>"'
print(pytesseract.image_to_string(Image.open('1.png'), lang='chi_sim', config=tessdata_dir_config))

err:

What happend?
After

>>> d.load()

OSError: [Errno 2] No such file or directory

Was attempting to use this with a multi-page tiff, but because of how Image.open() works, only the first page is turned into a string.

So I tried looping over n_frames using the seek() method, but was unsuccessful because pytesseract closes the image, so seek() throws ValueError: seek of closed file.

Perhaps pytesseract.py should check for n_frames, and convert the entire file by using the seek() method before closing? (Or at least offer that option).

As an example of what I was trying:

img = Image.open('path/to/my/img')
raw = ''
for i in range(img.n_frames):
    img.seek(i)
    raw+=pytesseract.image_to_string(img)

how to solve?

I installed pytesseract by pip. But when importing pytesseract, it occurs the errors "ValueError: Attempted relative import in non-package". I correctly installed tesseract. The python version is 2.7, tesseract 3.04.01. I don't konw how to do.
