如何在 python-tesseract 中设置 tessedit_write_images? [英] How to set tessedit_write_images in python-tesseract?

问题描述

我正在尝试设置 tessedit_write_images 但似乎无法做到，我在任何地方都看不到 tessinput.tif

我在做:

导入tesseractapi = tesseract.TessBaseAPI()api.Init(".","eng",tesseract.OEM_TESSERACT_ONLY)api.SetPageSegMode(tesseract.PSM_AUTO_OSD)api.SetVariable("tessedit_write_images", "T")

但是我已经尝试过使用True"、1"和其他一些变体，但似乎根本不起作用.

有什么帮助吗?

解决方案

tessedit_write_images 在 Tesseract 的源代码中只检查一次(通过 TessBaseAPI::ProcessPage()，见此处>..

所以你有两种方法:

1. 调用api.GetThresholdedImage()，返回的图片就是设置变量后调用ProcessPage保存的图片.
2. 只需调用api.ProcessPage()，它就会看到变量并输出tif.

I'm trying to set tessedit_write_images but can't seem to do it, i can't see the tessinput.tif anywhere

i'm doing:

import tesseract

api = tesseract.TessBaseAPI()
api.Init(".","eng",tesseract.OEM_TESSERACT_ONLY)
api.SetPageSegMode(tesseract.PSM_AUTO_OSD)
api.SetVariable("tessedit_write_images", "T")

but i've tried with "True", "1", and some more variations, doesn't seem to work at all.

Any help?

解决方案

tessedit_write_images is checked only once in Tesseract's source code (by TessBaseAPI::ProcessPage(), see here).

So you have two ways:

1. Call api.GetThresholdedImage(), and the returned image is what will be saved if you set the variable and call ProcessPage.
2. Just call api.ProcessPage(), and it will see the variable and output the tif.
