#How to install tesseract ocr in windows code#
Lang String - Tesseract language code string. If you pass object instead of file path, pytesseract will implicitly convert the image to RGB mode.
Image Object or String - PIL Image/NumPy array or file path of the image to be processed by Tesseract. Image_to_data(image, lang=None, config='', nice=0, output_type=Output.STRING, timeout=0, pandas_config=None) Gives a bit more control over the parameters that are sent to tesseract. Run_and_get_output Returns the raw output from Tesseract OCR. Image_to_alto_xml Returns result in the form of Tesseract’s ALTO XML format. Image_to_osd Returns result containing information about orientation and script detection. For more information, please check the Tesseract TSV documentation Image_to_data Returns result containing box boundaries, confidences, and other information. Image_to_boxes Returns result containing recognized characters and their box boundaries Image_to_string Returns unmodified output as string from Tesseract OCR processing Get_tesseract_version Returns the Tesseract version installed in the system. Get_languages Returns all currently supported languages by Tesseract OCR. image_to_string ( image, lang = 'chi_sim', config = tessdata_dir_config ) tessdata_dir_config = r '-tessdata-dir ""' pytesseract. run_and_get_output ( image, extension = 'txt', config = cfg_filename )Īdd the following config, if you have tessdata error like: “Error opening data file…” # Example config: r'-tessdata-dir "C:\Program Files (x86)\Tesseract-OCR\tessdata"' # It's important to add double quotes around the dir path. image_to_string ( image, config = custom_oem_psm_config ) # Example of using pre-defined tesseract config file with options cfg_filename = 'words' pytesseract. # Example of adding any additional options custom_oem_psm_config = r '-oem 3 -psm 6' pytesseract. If you need custom configuration like oem/ psm, use the config keyword. shape, img_cv, 'raw', 'BGR', 0, 0 ) print ( pytesseract. image_to_string ( img_rgb )) # OR img_rgb = Image. imread ( r '//digits.png' ) # By default OpenCV stores images in BGR format and since pytesseract assumes RGB format, # we need to convert from BGR to RGB format/mode: img_rgb = cv2.

Library usage: from PIL import Image import pytesseract # If you don't have tesseract executable in your PATH, include the following: pytesseract. Note: Test images are located in the tests/data folder of the Git repo. Additionally, if used as a script, Python-tesseract will print the recognized Supported by the Pillow and Leptonica imaging libraries, including jpeg, png, gif, bmp, tiff,Īnd others. It is also useful as a stand-alone invocation script to tesseract, as it can read all image types Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine.
That is, it will recognize and “read” the text embedded in images. Python-tesseract is an optical character recognition (OCR) tool for python.
