Python-tesseract is an optical character recognition (OCR) tool for python.
That is, it will recognize and "read" the text embedded in images.
Python-tesseract is a wrapper for `Google's Tesseract-OCR Engine <https://github.com/tesseract-ocr/tesseract>`_.
It is also useful as a stand-alone invocation script to tesseract, as it can read all image types
supported by the Pillow and Leptonica imaging libraries, including jpeg, png, gif, bmp, tiff,
and others. Additionally, if used as a script, Python-tesseract will print the recognized
text instead of writing it to a file.
USAGE
-----
**Quickstart**
*Note*: Test images are located in the ``tests/data`` folder of the Git repo.
.. code-block:: python
try:
from PIL import Image
except ImportError:
import Image
import pytesseract
# If you don't have tesseract executable in your PATH, include the following:
pytesseract.pytesseract.tesseract_cmd = r'<full_path_to_your_tesseract_executable>'
# Example tesseract_cmd = r'C:\Program Files (x86)\Tesseract-OCR\tesseract'
# Simple image to string
print(pytesseract.image_to_string(Image.open('test.png')))
# French text image to string
print(pytesseract.image_to_string(Image.open('test-european.jpg'), lang='fra'))
# In order to bypass the image conversions of pytesseract, just use relative or absolute image path
# NOTE: In this case you should provide tesseract supported images or tesseract will return error
print(pytesseract.image_to_string('test.png'))
# Batch processing with a single file containing the list of multiple image file paths
print(pytesseract.image_to_string('images.txt'))
# Get bounding box estimates
print(pytesseract.image_to_boxes(Image.open('test.png')))
# Get verbose data including boxes, confidences, line and page numbers
print(pytesseract.image_to_data(Image.open('test.png')))
# Get information about orientation and script detection
print(pytesseract.image_to_osd(Image.open('test.png')))
# Get a searchable PDF
pdf = pytesseract.image_to_pdf_or_hocr('test.png', extension='pdf')
# Get HOCR output
hocr = pytesseract.image_to_pdf_or_hocr('test.png', extension='hocr')
Support for OpenCV image/NumPy array objects
.. code-block:: python
import cv2
img = cv2.imread(r'/<path_to_image>/digits.png')
print(pytesseract.image_to_string(img))
# OR explicit beforehand converting
print(pytesseract.image_to_string(Image.fromarray(img))
If you need custom configuration like `oem`/`psm`, use the **config** keyword.
.. code-block:: python
# Example of adding any additional options.
custom_oem_psm_config = r'--oem 3 --psm 6'
pytesseract.image_to_string(image, config=custom_oem_psm_config)
Add the following config, if you have tessdata error like: "Error opening data file..."
.. code-block:: python
# Example config: r'--tessdata-dir "C:\Program Files (x86)\Tesseract-OCR\tessdata"'
# It's important to add double quotes around the dir path.
tessdata_dir_config = r'--tessdata-dir "<replace_with_your_tessdata_dir_path>"'
pytesseract.image_to_string(image, lang='chi_sim', config=tessdata_dir_config)
**Functions**
* **get_tesseract_version** Returns the Tesseract version installed in the system.
* **image_to_string** Returns the result of a Tesseract OCR run on the image to string
* **image_to_boxes** Returns result containing recognized characters and their box boundaries
* **image_to_data** Returns result containing box boundaries, confidences, and other information. Requires Tesseract 3.05+. For more information, please check the `Tesseract TSV documentation <https://github.com/tesseract-ocr/tesseract/wiki/Command-Line-Usage#tsv-output-currently-available-in-305-dev-in-master-branch-on-github>`_
* **image_to_osd** Returns result containing information about orientation and script detection.
* **run_and_get_output** Returns the raw output from Tesseract OCR. Gives a bit more control over the parameters that are sent to tesseract.
**Parameters**
``image_to_data(image, lang=None, config='', nice=0, output_type=Output.STRING, timeout=0)``
* **image** Object, PIL Image/NumPy array of the image to be processed by Tesseract
* **lang** String, Tesseract language code string
* **config** String, Any additional configurations as a string, ex: ``config='--psm 6'``
* **nice** Integer, modifies the processor priority for the Tesseract run. Not supported on Windows. Nice adjusts the niceness of unix-like processes.
* **output_type** Class attribute, specifies the type of the output, defaults to ``string``. For the full list of all supported types, please check the definition of `pytesseract.Output <https://github.com/madmaze/pytesseract/blob/master/src/pytesseract.py>`_ class.
* **timeout** Integer or Float, duration in seconds for the OCR processing, after which, pytesseract will terminate and raise RuntimeError.
INSTALLATION
------------
Prerequisites:
- Python-tesseract requires Python 2.7 or Python 3.5+
- You will need the Python Imaging Library (PIL) (or the `Pillow <https://pypi.org/project/Pillow/>`_ fork).
Under Debian/Ubuntu, this is the package **python-imaging** or **python3-imaging**.
- Install `Google Tesseract OCR <https://github.com/tesseract-ocr/tesseract>`_
(additional info how to install the engine on Linux, Mac OSX and Windows).
You must be able to invoke the tesseract command as *tesseract*. If this
isn't the case, for example because tesseract isn't in your PATH, you will
have to change the "tesseract_cmd" variable ``pytesseract.pytesseract.tesseract_cmd``.
Under Debian/Ubuntu you can use the package **tesseract-ocr**.
For Mac OS users. please install homebrew package **tesseract**.
| Installing via pip:
Check the `pytesseract package page <https://pypi.python.org/pypi/pytesseract>`_ for more information.
.. code-block:: bash
$ (env)> pip install pytesseract
| Or if you have git installed:
.. code-block:: bash
$ (env)> pip install -U git+https://github.com/madmaze/pytesseract.git
| Installing from source:
.. code-block:: bash
$> git clone https://github.com/madmaze/pytesseract.git
$ (env)> cd pytesseract && pip install -U .
| Install with conda (via `conda-forge <https://anaconda.org/conda-forge/pytesseract>`_):
.. code-block:: bash
$> conda install -c conda-forge pytesseract
TESTING
-------
To run this project's test suite, install and run ``tox``. Ensure that you have ``tesseract``
installed and in your PATH.
.. code-block:: bash
$ (env)> pip install tox
$ (env)> tox
