# write the grayscale image to disk as a temporary file so we canįirst, we load -image from disk into memory ( Line 17) followed by converting it to grayscale ( Line 18). # make a check to see if median blurring should be done to remove # check to see if we should apply thresholding to preprocess the Gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # load the example image and convert it to grayscale Next we’ll load the image, binarize it, and write it to disk. This switch is optional and for this tutorial and can accept two values: thresh (threshold) or blur. -preprocess: The preprocessing method.-image: The path to the image we’re sending through the OCR system.Our command line arguments are parsed on Lines 9-14. The Image class is required so that we can load our input image from disk in PIL format, a requirement when using pytesseract. # construct the argument parse and parse the argumentsĪp.add_argument("-i", "-image", required=True,Īp.add_argument("-p", "-preprocess", type=str, default="thresh", Let’s begin by creating a new file named ocr.py: # import the necessary packages Free pdf ocr tool 2017 code#Let’s move forward by reviewing some code that segments the foreground text from the background and then makes use of our freshly installed pytesseract. This is definitely a bit hackish, but it gets the job done for us. If you take a look at the project on GitHub you’ll see that the library is writing the image to a temporary file on disk followed by calling the tesseract binary on the file and capturing the resulting output. Rather, it simply provides an interface to the tesseract binary. Note: pytesseract does not provide true Python bindings. Free pdf ocr tool 2017 install#Next let’s install Pillow, a more Python-friendly port of PIL (a dependency) followed by pytesseract. In this case, our virtualenv is named cv. If you’re using a virtual environment (which I highly recommend so that you can separate different projects), use the workon command followed by the appropriate virtual environment name. To install pytesseract we’ll take advantage of pip. Let’s begin by getting pytesseract installed. Installing the Tesseract + Python “bindings” To download the source code + example images to this blog post, be sure to use the “Downloads” section below. Next, we’ll develop a simple Python script to load an image, binarize it, and pass it through the Tesseract OCR system.įinally, we’ll test our OCR pipeline on some example images and review the results. Free pdf ocr tool 2017 how to#This blog post is divided into three parts.įirst, we’ll learn how to install the pytesseract package so that we can access Tesseract via the Python programming language.
