I'm trying to use the command vision.CascadeObjectDetector to create a face detector object but when I do
faceDetector = vision.CascadeObjectDetector();
I encounter an error saying:
Error using vision.CascadeObjectDetector
License checkout failed.

I just recently upgraded from trial to student version (Bought for $100). This command is from the Computer Vision Toolbox, and is included in the student version right? So I assume that I should be able to use it. Any solution??

As you can see, I have the computer vision system toolbox, so I'm not sure why commands from that toolbox are not working

The license might not have gotten installed properly. I suggest deactivating and reactivating.

I recommend trying the following in MATLAB command window
>> license('checkout','video_and_image_blockset')
If the answer is not 1 from MATLAB, contact Installation support of MathWorks.

How to solve this error?
My Code is working well on MATLAB 2015a but when I run it on MATLAB 2017a, I got this error.
Error using imwrite
(line 420)
Expected DATA to be one of these types: numeric, logical. Instead its type was vision.CascadeObjectDetector.
Error in Trainingcode (line 38)
imwrite(Mouth,strcat('E:\SVM\JAFFE Local Features\', int2str(i),int2str(j), '.tiff'));
