Pytesseract - Using user patterns

╄→гoц情女王★ 提交于 2021-02-19 04:18:55
问题 I'm trying to use tesseract's user-patterns with pytesseract but can't seem to get the command working. This seems like it should be fairly straight forward but the documentation is sparse I'm on tesseract 3.05.01. Doing this doesn't work: pytesseract.image_to_string(image, config='--oem 0 bazaar --user-patterns ./timestamps.user_patterns') I have a bazaar file in /usr/local/share/tessdata/configs/bazaar that says this: load_system_dawg T load_freq_dawg T user_words_suffix user-words user

Image to Text - Pytesseract struggles with digits on windows

岁酱吖の 提交于 2021-02-11 12:03:28
问题 I'm trying to preprocess frames of a game in real-time for a ML project. I want to extract numbers from the frame, so I chose Pytesseract, since it looked quite good with text. Though, no matter how clear I make the text, it won't read it correctly. My code looks like this: section = process_screen(screen_image)[1] pixels = rgb_to_bw(section) #Makes the image grayscale pixels[pixels < 200] = 0 #Makes all non-white pixels black tess.image_to_string(pixels) => 'ye ml)' At best it outputs "ye ml

How to improve OCR with Pytesseract text recognition?

问题 Hi I am looking to improve my performance with pytesseract at digit recognition. I take my raw image and split it into parts that look like this: The size can vary. To this I apply some pre-processing methods like so image = cv2.imread(im, cv2.IMREAD_GRAYSCALE) image = cv2.GaussianBlur(image, (1, 1), 0) kernel = np.ones((5, 5), np.uint8) result_img = cv2.blur(img, (2, 2), 0) result_img = cv2.dilate(result_img, kernel, iterations=1) result_img = cv2.erode(result_img, kernel, iterations=1) and

问题 I'm trying to read text from an image, using OpenCV and Pytesseract, but with poor results. The image I'm interested in reading the text is: https://www.lubecreostorepratolapeligna.it/gb/img/logo.png This is the code I am using: pytesseract.pytesseract.tesseract_cmd = r'D:\Program Files\pytesseract\tesseract.exe' image = cv2.imread(path_to_image) # converting image into gray scale image gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) cv2.imshow('grey image', gray_image) cv2.waitKey(0) #

Is it possible to check orientation of an image before passing it through pytesseract ocr module

别等时光非礼了梦想. 提交于 2021-02-08 03:45:58
问题 For my current ocr project I tried using tesserect using the the python cover pytesseract for converting images into text files. Up till now I was only passing well straight oriented images into my module at it was able to properly figure out text in that image. But now as I am passing rotated images it is not able recognize even a single word. So to get good result I need to pass images only with proper orientation. Now I want to know that is there any method to figure out the orientation of

How to deploy pytesseract to Heroku

一笑奈何 提交于 2021-02-07 10:25:44
问题 I have a Python app which words great via Localhost on my machine. I am trying to deploy it to Heroku. However it does not seem possible to accomplish this (I have spent approx 30 hours trying now). The problem is Tesseract OCR. I am using the pytesseract wrapper, and my code utilises this. However, no matter what I try, it does not seem to be possible to use pytesseract when it is uploaded to Heroku. Could anyone either suggest how to go about deploying a Hello World Tesseract OCR Python app
