我尝试使用 matlab 检测图像中的人脸。为此，我找到了许多演示。所有演示都使用 vision.CascadeObjectDetector 类。但是我的 matlab 总是抛出异常，即“未定义的变量“视觉”或类“vision.CascadeObjectDetector”，甚至试图在命令窗口中调用视觉类

计算机视觉系统工具箱已安装。

问题出在哪里，我该如何解决？

我不认为 vision.CascadeObjectDetector 在 R2011b 中可用。它可从 R2012a 获得。您正在运行的演示是否提到任何最低版本要求？

此错误强烈表明未安装计算机视觉系统工具箱。

要确保它已安装，ver请在 Matlab 命令提示符下键入。对我来说，这输出：
