To specify the language you need your OCR output in, use the -l LANG argument in the config where LANG is the 3 letter code for what language you want to use. So, I created a function for ocr with pytesseract and when saving to a file added parameter encoding='utf-8' so my function now looks like this: How to use the pytesseract. image_to_string (img). 92211992e-01 2. Here's an example. tesseract myscan. 7 Treat the image as a single text line. As evident from the above images, the black areas are the places that are removed from the background. THRESH_OTSU) # Use Tesseract to extract text from the screenshot code =. image_to_string(img) print(text) There is no argument like confidence that you can pass to the pytesseract image_to_string(). Unfortunately Q is recognized as O. I have tried few preprocessing techniques like adaptive thresholding, erosion, dilation etc. for line in result: print (line [1] [0]) In this example, we first load the OCR model using the OCR () function provided by PaddleOCR. Teams. This script does the following: Load input image from the disk. # stripping the output string is a good practice as leading and trailing whitespaces are often found pytesseract. jpg'), lang='spa')) Maybe changing the settings (psm oem) or maybe some preprocessing, I already tried some but not much better. Improve this answer. In text detection, our goal is to automatically compute the bounding boxes for every region of text in an image: Figure 2: Once text has been localized/detected in an image, we can decode. There is an option in the Tesseract API such that you are able to increase the DPI at which you examine the image to detect text. frame = frame[900:1000, 450:500] scale_percent = 200 # percent of I've had the same problem as you but I had to save the output of pytesseract to a file. image_to_string (Image. Example found by google. 複数の言語を使用して文字認識を行う. 9 1. Text localization can be thought of as a specialized form of object detection. The example file, is one of a lot of image files that will be processed, is a 72ppi grayscale historical document of high contrast. None, iterations=2) # OCR with assuming the image as a single uniform block of text txt = pytesseract. what works for me: after I install the pytesseract form tesseract-ocr-setup-3. You can do this by passing additional parameters to the image_to_string. Ran into a similar issue and resolved it by passing --dpi to config in the pytesseract function. image_to_string(img, lang="eng") return result Last words.
