Hi,
In my manual-procedure : https://github.com/stefanache/using-tesseract-ocr-python
seen that can create one pipeline with scope to detect the text from images with good accurance.
So in this procedure will discuss about even of "Using OpenCV's EAST for text-recognition(OCR) with tesseract"
Remember that :
This EAST method(https://www.pyimagesearch.com/2018/08/20/opencv-text-detection-east-text-detector/)
will be part of this pipeline:
Input image -> OpenCV's EAST(Text Detector) -> Extract Text ROIs -> Tesseract v.4 OCR with LSTM(text recognizer) -> OpenCV+Tesseract OCR Results
https://www.pyimagesearch.com/2018/09/17/opencv-ocr-and-text-recognition-with-tesseract/
https://github.com/efviodo/opencv-text-recognition
exist and web opencv OCR:
https://github.com/tamaUdon/Web_OCR_app/tree/master/app
and can use google search for others with this phrase:
"github adrian rosebrock ocr Tesseract"
or with phrase wich include specific file which contain the pretrained model:
"frozen_east_text_detection.pb"
1. install the Open CV : https://github.com/stefanache/install_OpenCV4_on_w10Pro
2. install tesseract: https://github.com/stefanache/install_Tesseract4_for_Python3.7
and using it https://github.com/stefanache/using-tesseract-ocr-python
But not discuss about the versions wich need to have to resolve the compatibility and finally
to can have one robust solution.
For that if you consult the https://github.com/efviodo/opencv-text-recognition then see this file
requirement.txt with this content:
pillow==7.0.0
pytesseract==0.3.2
imutils==0.5.3
opencv-python==4.2.0.32
this file can be used to ensure that have all these versions with command :
pip install -r requirements.txt
From the my github repository root directory missed the pretrained model(frozen_east_text_detection.pb)
because is large/big file but you can download from https://github.com/oyyd/frozen_east_text_detection.pb
Also I created the batch file(text_recognition_RUN.bat) for my OS(windows 10 pro) to can have idea about
how using the text_recognition.py with python and how install/update the requirement.txt
To run this batch call from windows cmd.exe and then simply type the command:
C:\Users\{user}> text_recognition_RUN.bat
In fact you can find and download the entire project at https://github.com/efviodo/opencv-text-recognition
My repository contain in plus the above batch file (text_recognition_RUN.bat) which contain some calls for
this efviodo's tutorial
