Matlab2018a中未定义变量"vision“或"vision.OpticalFlow”类
提问于 2018-04-17 17:21:34
我在我的Ubuntu机器上安装了Matlab2018a (linux版本)。我试图计算一个视频的光流，在这里我被呈现出上述的错误。谷歌搜索显示，这可能是由两个问题造成的，要么是Matlab的旧版本(比如2009年)，要么是计算机视觉工具箱可能没有安装。
我有最新版本的Matlab，并且仍然会收到这个错误，我还安装了所需的工具箱，从ver的输出命令中可以看到。

我找出了为什么不起作用..。vision.OpticalFlow已从最新版本的Matlab中删除，如果使用Horn-Schunck method，则建议使用opticalFlowHS。
