为 Tesseract 提供模式 [英] Provide Pattern for Tesseract

问题描述

我同时使用 go 和 tesseract.我有类似的东西2^3 或 22^55

I'm using go and tesseract together. I have something like 2^3 or 22^55

而且 Tesseract 有时仍然会出现白名单错误，所以我正在寻找一种方法来提供模式，我阅读了 FaQ 并在集市上尝试了建议的选项.

And Tesseract is still sometimes wrong with a white list so I'm looking for a way to provide pattern I read through the FaQ and tried the suggested option with the bazaar.

我的模式文件如下所示:

My Pattern file looks like this:

\d\d^\d\d
\d^\d\d
\d^\d
\d^\d\d

但不知何故它仍然不起作用.是否有任何提示可以使其工作，或者是实现这一点以生成新语言文件的唯一方法.

But somehow It still doesnt work. Are there any tips to get it working or is the only way to realize this to generate a new language file.

推荐答案

不是开发者，请见谅.

不久前我正在研究一个类似的问题，发现源代码中的描述令人困惑，因为默认情况下 tesseract 需要在模式前 4 个以上的常量字符.它甚至提供了在默认条件下不起作用的示例.

I was looking into a similar issue a while ago and found that the description in the source code is confusing as tesseract by default needs 4+ constant characters in front of the pattern. It even provides examples that would not work under default conditions.

但是，这是可配置的，如下所述:trie.h 代码

However this is configurable as is described in: The trie.h code

kSaneNumConcreteChars 我很确定这就是你想要的参数.

kSaneNumConcreteChars I am pretty sure was the parameter you are after.

希望这会有所帮助.
