my faceDetector = vision.CascadeObjectDetector does not work
显示 更早的评论
I have MATLAB R2015a and the command faceDetector = vision.CascadeObjectDetector(); does not work in it. I do have the computer vision toolbox. The error display says Undefined variable "vision" or class "vision.CascadeObjectDetector".

Do you have the Computer Vision System Toolbox installed?

Do you see Computer Vision System Toolbox among the installed products?
