在我的 AR 项目中，我必须将输入检测为对象？？？我在 Octave 平台上尝试了一个代码，但显示错误为

错误：'detectSURFFeatures'在第 10 行第 14 列附近未定义错误：在第 10 行第 13 列从 plz 调用

我安装了图像采集包和图像包，然后还使用 rgb2gray() 将彩色图像转换为灰度图像

但是我无法在 octave 中安装计算机视觉系统工具如何在 octave 上安装该工具？你能帮我解决这个问题吗？这是我的编码............

    referenceImage=imread('l.jpg');

imshow(referenceImage);
