Hello,
I have some questions toward the lecture Shape from Texture.
1) P10-11. About tilt and slant. I am a bit confusing about the definition of tilt and slant. It seems that what I find in paper is contradict with what the professor says in the lecture. I find the definition online as following:
It seems that the tilt means the orientation of the surface normal projected into the image plane, while slant means the angle between the object plane and the image plane. However, I remember that the definitions of "tilt" and "slant" provided by the professor in class are opposite to the information mentioned above. I would like to confirm what is the correct definition of tilt and slant?
2) P15. I do not understand the equation:
What is the vector [x0, y0, z0] refer to in the equation? Does it mean the normal at location (x0, y0, z0)?
Thanks in advance!
