DGGT's biggest breakthrough is that it gets rid of the dependence on scene-by-scene optimization, camera calibration, and short frame windows of traditional solutions.

Analysis

This paper establishes a connection between discrete-time boundary random walks and continuous-time Feller's Brownian motions, a broad class of stochastic processes. The significance lies in providing a way to approximate complex Brownian motion models (like reflected or sticky Brownian motion) using simpler, discrete random walk simulations. This has implications for numerical analysis and understanding the behavior of these processes.

For any Feller's Brownian motion that is not purely driven by jumps at the boundary, we construct a sequence of boundary random walks whose appropriately rescaled processes converge weakly to the given Feller's Brownian motion.
