I am attempting to integrate optical flow into my MatLab program. opticalFlowLK is supposed to create an object that can be used for the estimateFlow function, however, matlab thinks it is an undefined variable or function.

opticFlow = opticalFlowLK;

“Unrecognized function or variable ‘opticalFlowLK'”

I am unsure whether it is my version of Matlab or if I need to integrate it into my program in another way.

I have also tried adding the built in noise thresholding:

opticFlow = opticalFlowLK('NoiseThreshold',0.05); 

But that is also not recognized.
