I have install opencv also and give following syntax as directed in github but is showing below error
mex generateEllipseCandidates.cpp -IC:\Program Files\MATLAB\opencv-2.4.9\build\include -IC:\Program Files\MATLAB\opencv-2.4.9\build\include\opencv -IC:\Program Files\MATLAB\opencv-2.4.9\build\include\opencv2 -lC:\Program Files\MATLAB\opencv-2.4.9\build\x64\vc11\lib -IC:\Program Files\MATLAB\R2019b\extern\include -lC:\Program Files\MATLAB\R2019b\extern\lib\win64\microsoft -lopencv_core249 -lopencv_highgui249 -lopencv_imgproc249 -llibmwlapack.lib
Error using mex
C:\ProgramFiles\MATLAB\High-quality-ellipse-detection-master\High-quality-ellipse-detection-master\Files\MATLAB\opencv-2.4.9\build\include
not found; check that you are in the correct current folder, and check the spelling of 'C:\Program
Files\MATLAB\High-quality-ellipse-detection-master\High-quality-ellipse-detection-master\Files\MATLAB\opencv-2.4.9\build\include'.

Could be because of the spaces in the file paths. Try encapsulating them in double quotes.
mex generateEllipseCandidates.cpp -I"C:\Program Files\MATLAB\opencv-2.4.9\build\include" ...
