易语言OCR证件照文字识别

<div id="content_views" class="htmledit_views">
                  <h3>&nbsp;&nbsp;一.引言</h3>
<p>文字识别，也称为光学字符识别（Optical Character Recognition, OCR），是一种将不同形式的文档（如扫描的纸质文档、PDF文件或数字相机拍摄的图片）中的文字转换成可编辑和可搜索的数据的技术。随着技术的发展，文字识别技术已经成为信息管理、自动化办公和智能系统的关键组成部分。</p>
<h3>二.简介</h3>
<p>为了易于集成和使用，我们将文字识别OCR封装为DLL（动态链接库）。这种封装方式不仅保留了算法的性能优势，还提供了跨平台和跨语言的兼容性，目前支持编程语言如下：</p>
<ul><li>C++</li><li>Python</li><li>易语言</li></ul>
