Improving OCR Results with Basic Image Processing
Witryna12 paź 2024 · image processing to improve tesseract OCR accuracy 我一直在使用tesseract将文档转换为文本。 文档的质量千差万别,我正在寻找有关哪种图像处理可以改善结果的提示。 我注意到,像素化程度很高的文本 (例如,由传真机生成的文本)对于tesseract特别难以处理-大概字符的所有锯齿状边缘都会混淆形状识别算法。 哪种图 … 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. great lakes naval recruit training command
