Can I cite one of the illustrative figure from the website in OpenCV in my research paper?
I need to explain the pinhole camera model in my research paper and the figure in the Camera Calibration and 3D Reconstruction page offers perfect illustration:
It is from the page:
OpenCV: Camera Calibration and 3D Reconstruction
Do I need to ask for permission to use this figure? If so, where should I look for help?
Thanks a lot.
