Hello,

In the slide P48 of lecture Shape from Shading. I am confusing about the new surface expression "λf(u,v) + μu + vv" with A = A. I consider the expression of A should be change A by solving the integrability constraint. The last element should be λ(an arbitrary number) instead of 1. Is it correct? Thanks in advance.

Hello,
You are correct, thank you for noticing this typo. We will update the slides. You can read the correct derivation in section 4 of this document.

Note that the conclusion (your highlighted text) is still the same, and that the full derivation is beyond the scope of the class.

I hope this helps,
Benoit
