它说:
最快的方法(可能不是理想的方法)是执行以下步骤:
-使用OpenCV检测纸张或文本区域；
-执行必要的处理以校正图像(如有必要)；
-将图像另存为TIFF;
-最后，调用Tesseract cmd-line应用程序，将TIFF图像作为参数传递，以开始文本识别过程.

It says:
The fastest way (maybe not the ideal) is to implement the following steps:
- Use OpenCV to detect the paper sheet or the text area;
- Perform any processing necessary to deskew the image (if necessary);
- Save the image to disk as TIFF;
- and finally, call Tesseract cmd-line application passing the TIFF image as parameter to start the text recognition process.
