When you want to verify program operation such as machine learning, if you have a Google account Since it was a work check, it is also nice not to pollute the local machine.

It was also necessary to install a Japanese dictionary, but at Colaboratory This time, in order to use Tesseract-OCR, you can import the library or Tesseract-OCR itself can also improve recognition accuracy by reflecting fonts and other information in learning. In terms of accuracy, the results were lower than in English. The parenthetical letters in the footnotes are generally garbled. In the case of Japanese, it can be read roughly, but the "ah" in hiragana becomes lowercase, TextBuilder ( tesseract_layout = 6 ) ) print ( txt ) open ( filename ), lang = "jpn", builder = pyocr.

We will actually write the code in Colaboratory. We will also introduce "pyocr", a Python wrapper of Tesseract-OCR this time. This time, we will also incorporate training data in Japanese. Tesseract-OCR does not support Japanese by default. Wrappers available for various programming languages
In 2006, Google fixed a bug and made it open source.Ī library with a history and discipline. This engine was developed by HP from 1985 to 1995.Īfter that, HP withdrew from the OCR business and left it for nearly 10 years.

Open source OCR library (Apache License v2.0).However, it is not interesting to use Colaboratory vaguely, so this time I will put the OCR engine Tesseract-OCR on the environment and run it.īy the way, a brief introduction to Tesseract-OCR is the following library. It can be set in the item "Change runtime type" in the runtime menu.Įxecuting Unix commands, like Jupyter Notebook, is also called "!" It is feasible if it is preceded by. The screen and operability are almost the same as Jupyter Notebook.Īnalysis processing in notes can also be done using hardware accelerators. When you select "Create a new notebook of Python 3" from the file menu, the following edit screen will be displayed. While logged in with your Google account, try accessing Colaboratory.

In the previous blog, I used Jupyter Notebook to check the operation of the program in a browser in the local environment.Ĭolaboratory is very useful because if you have a Google account, you can use the environment equivalent to Jupyter Notebook without software installation. Thanks in advance.This time, we will deal with Colaboratory, which Google provides for machine learning and research.

Then I tried to install tesseract using the command ->pip install tesseract-ocr. When I searched this error, I found Pyocr looks for the OCR tools (Tesseract, Cuneiform, etc) installed on your system and just tells you what it has found. Now the project runs with error : No OCR tool found I had added the required libraries based on requirement. I have downloaded Mayan EDMS-Electronic Document Management System from GitHub and I configured project using Django server.
