I am using MATLAB version 2018b. I have the Computer Vision Toolbox installed as confirmed by using the ver command. However, upon using the following code:
hhoughtrans = vision.HoughTransform(pi/360,'ThetaRhoOutputPort', true);
I receive the following error message: Undefined variable "vision" or class "vision.HoughTransform".
Similarly, when using:
hhoughlines = vision.HoughLines('SineComputation','Trigonometric function');
I receive: Undefined variable "vision" or class "vision.HoughLines".
My conclusion is that vision.HoughTransform and vision.HoughLines are no longer supported though I haven't seen anywhere something to the contrary. Is this conclusion correct or could there be another issue?
