Unable to be resolve vision.Pyramid in gaussianSpacialFilter.m

[Muskan0510]

Hi, I wanted to learn from the process and pipeline you established for heart rate detection.

Anxiety-Detection/Code/gaussianSpatialFilter.m

Line 45 in 420eebd

gPyramid = vision.Pyramid('Operation', 'Reduce', 'PyramidLevel', pyrLevel);

This line gives an error "Unable to be resolve vision.Pyramid in gaussianSpacialFilter.m"

Could you let me know the necessary libraries or function files needed for resolving the error? Is there any alternate matlab function which achieves similar functionality as implemented in the above lines of code?
