Witryna11 cze 2024 · Let’s see how we can increase the existing accuracy of our OCR engine: Scaling of image Image Rescaling is important for image analysis. Most OCR engines give an accurate output of the image which has 300 DPI (Dots per inch). Keeping DPI lower than 200 or greater than 600 may result in inaccurate results. Increase contrast Witrynaworking on tesseract. I think that preprocessing of image or downscaling the original image decreases efficiency of algorithm. Preprocessing of image also slows down the overall execution time. I think you are training the images well. What you can do is to train the tesseract of different character sizes.
