这时,我们可以结合OCR(Optical Character Recognition,光学字符识别)技术,使用如Tesseract这样的OCR引擎,通过PIL(Python Imaging Library)或OpenCV来预处理图像,然后使用Tesseract识别图像中的文字,从而提高文本提取的准确性。 案例步骤 安装必要的库:首先,确保安装了PyPDF2、PDFMiner、PIL、OpenCV和pytesseract。 读取PDF文件...

pipeline = keras_ocr.pipeline.Pipeline() 步骤4:进行文本识别 使用已加载的管道对图像执行文本识别。你可以将单个图像或图像列表传递给 recognize() 函数。 images = ['image1.jpg', 'image2.jpg'] # List of image file paths predictions = pipeline.recognize(images) 这将返回每个图像的预测,包含有关检测...
