    Java摄像开源框架（文档、案例、Jar包）、个人项目工程（JavaFX）、原始实例（JavaFX）：https://download.csdn.net/download/haoranhaoshi/10898408

    摄像、拍照、人脸识别、人脸库对比： https://download.csdn.net/download/haoranhaoshi/10911079    

本篇在系列文章三的基础上进行扩展，拍照存储后产生人脸库，人脸图片保存时命名为个人姓名，点击人脸识别在人脸库中进行对比，展示对比结果。如果人脸库中有重复的人脸，也可在对比结果中检测到。
人脸库对比效果：

项目为IDEA搭建，终极工程可在如下地址下载（包括Java摄像、拍照、人脸识别、人脸库对比）：
