Latest Patents

Henzler is named on 1 patent: “Camera Parameter Preconditioning for Neural Radiance Fields.” The patent describes a method for improving model training by analyzing camera parameters across a collection of images. It determines a covariance matrix for those parameters using projected points, then applies a whitening algorithm to identify a preconditioning matrix that makes the covariance matrix approximately equal to an identity matrix. During optimization, the method applies the inverse of that matrix in the forward prediction pass and the matrix itself in the backward gradient pass.

Career Highlights

The disclosed invention focuses on conditioning camera parameters to support optimization in neural radiance field training. By transforming parameter values before and during optimization, the approach aims to make the training process more effective.
