my faceDetector = vision.Cas​cadeObject​Detector does not work

3 visualizzazioni (ultimi 30 giorni)
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?

If you type

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