We derive the Fokker-Planck equation (forward equation) and the backward equation. FPE is central in diffusion models to guarantee the correctness of image generation algorithm. Despite its extensive use in diffusion literature, the FPE background is not often presented in details.

Direct Linear Transformation (DLT) problems in computer vision involve messy coefficients in the linear system of equations. Appropriate use of an orthogonalization routine and einsum simplifies the implementation; it also helps to make the code more standardized and more readable.

Finding the intersection of two lines in 3D in a less ad-hoc manner using surface constraints and QR / SVD factorization.
