\begin{block}{Inverse rendering here}
|
|
\begin{itemize}
|
|
\item Fit camera pose, material parameters and light source intensity
|
|
\item Scene: Strong indirect illumination and non lambertian materials
|
|
\item Initial guess: Assign almost all objects a white color, arbitrary camera pose
|
|
\item 177 parameters in total
|
|
\item Absolute difference as loss function and ADAM optimizer
|
|
\item Start at a resulution of $64\times 64$ and linearly increase to $512\times 512$ in 8 steps\\
|
|
$\implies$ Avoid getting stuck in local minima of the loss function
|
