Treat the image as a single text line, bypassing hacks that are Tesseract-specific. Introduction OCR = Optical Character Recognition. that'll give you info on what's black text and what's reflective background. 1 Answer. Useful parameters. Still doesn't work unfortunately. Regression parameters for the second-degree polynomial: [ 2. I am performing ocr on cropped images, using tesseract and pytesseract (in python). You can produce bounding rectangles enclosing each character, the tricky part is to successfully and clearly segment each character. You could also have a method to delete the variable from the file and thus. 92211992e-01 2. The idea is to obtain a processed image where the text to extract is in black with the background in white. We only have a single Python script here,ocr_and_spellcheck. >>> img. 2. . open ("1928_-1. A simple Otsu's threshold to obtain a binary image then an inversion to get the letters in black and the background in white seems to work. size (217, 16) >>> img. open ('image. Lesson №4. Turned out that the file color profile is different from the original image. We simply use image_to_string without any configuration and get the result. image_to_string Returns the result of an OCR Tesseract executed on the string image; image_to_boxes Returns a result containing recognized characters and their box. The image to string () method converts the image text into a Python string, which you can then use however you like. When loading an image directly onto the pytesseract. ) img = cv2. pytesseract. image = cv2. For this problem, Gaussian blur did not help you. Python-tesseract is actually a wrapper class or a package for Google’s Tesseract-OCR Engine. image_to_string(thr, config='--psm 6') For more read: Improving the quality of the output. Regression parameters for the second-degree polynomial: [ 2.
