|
||
|
||
Tesseract-OCR
|
||
Google维护的开源OCR引擎，支持Java，Python等语言调用
|
||
|
||
|
||
Tess4J
|
||
封装了Tesseract-OCR ，支持Java调用
|
||
|
||
|
||
二.Tesseract-OCR 的特点
|
||
Tesseract支持UTF-8编码格式，并且可以“开箱即用”地识别100多种语言
|
||
|
||
Tesseract支持多种输出格式：纯文本，hOCR（HTML），PDF等
|
||
|
||
官方建议，为了获得更好的OCR结果，最好提供给高质量的图像
|
||
|
||
Tesseract进行识别其他语言的训练，具体的训练方式请参考官方提供的文档：https://tesseract-ocr.github.io/tessdoc/

二.可选方案

|
||
|
||
方案
|
||
说明
|
||
|
||
|
||
|
||
数据库模糊查询
|
||
效率太低
|
||
|
||
|
||
String.indexOf(“”)查找
|
||
数据库量大的话也是比较慢
|
||
|
||
|
||
全文检索
|
||
分词再匹配
|
||
|
||
|
||
DFA算法
|
||
确定有穷自动机(一种数据结构)
|
||
|
||
|
||
三. DFA算法1.简介DFA全称为：Deterministic Finite Automaton,即确定有穷自动机。
|
||
存储：一次性的把所有的敏感词存储到了多个map中，就是下图表示这种结构
|
||
敏感词：冰毒、大麻、大坏蛋

二.简单示例1.创建一个maven工程前置条件: Java环境，Maven环境，IDEA开发工具
|
||
2.在pom.xml文件中引入udf的依赖12345<dependency> <groupId>org.apache.hive</groupId> <artifactId>hive-exec</artifactId> <version>0.13.1</version></dependency>
|
||
|
||
3.编写udf函数创建一个java类继承UDF类，实现evaluate()方法，evaluate()方法可以重载

二.安装教程1.开启WSL相关功能
|
||
|
||
2.在微软应用商店下载并安装Ubuntu
|
||
|
||
3.下载完成后打开Ubuntu，设置用户名和密码就可以使用了，下次打开直接搜索Ubuntu这个应用，打开即可
|
||
用户名要小写，下面我们可以看到如果使用大写的用户名，会一直提示我们使用小写的用户名
|
||
|
||
4.使用Windows Terminal操作Ubuntu
|
||
下载Windows Terminal
|
||
|
||
使用Windows Terminal打开Ubuntu界面
|
||
|
||
三.FinalShell连接本机Ubuntu1.先卸载重装一遍ssh服务，这里不是很确定是不是自带ssh服务有没有问题 ，这里使用root
|
||
1234sudo -s #切换到管理员用户apt-get remove openssh-serverapt-get install openssh-serverapt-get update #执行上面的指令出现404错误的时候可以执行一下这一条指令，然后再执行上面的命令
|
