opticalFlowClass=vision.OpticalFlow（'OutputValue'，复杂形式的水平和垂直分量，'Method'，'Horn Schunck'）计算OpticalFlow时，我得到以下错误：
Undefined variable "vision" or class "vision.OpticalFlow".
Error in Video2OpticalFlow (line 28)
opticalFlowClass = vision.OpticalFlow('OutputValue', ...
有人能告诉我为什么我会犯这个错误吗？
谢谢我找到了它不起作用的原因vision.OpticalFlow
已从最新版本的Matlab中删除，如果使用Horn-Schunck方法，建议使用opticalFlowHS
