Seeing the World through Your Eyes
This work addresses the challenge of non-line-of-sight imaging for applications like surveillance or human-computer interaction, though it appears incremental as it builds on existing reflection-based methods.
The paper tackled the problem of reconstructing 3D scenes outside a camera's direct line of sight by using reflections in human eyes from portrait images, achieving feasibility in recovering scenes through experiments on synthetic and real-world data with varied eye colors.
The reflective nature of the human eye is an underappreciated source of information about what the world around us looks like. By imaging the eyes of a moving person, we can collect multiple views of a scene outside the camera's direct line of sight through the reflections in the eyes. In this paper, we reconstruct a 3D scene beyond the camera's line of sight using portrait images containing eye reflections. This task is challenging due to 1) the difficulty of accurately estimating eye poses and 2) the entangled appearance of the eye iris and the scene reflections. Our method jointly refines the cornea poses, the radiance field depicting the scene, and the observer's eye iris texture. We further propose a simple regularization prior on the iris texture pattern to improve reconstruction quality. Through various experiments on synthetic and real-world captures featuring people with varied eye colors, we demonstrate the feasibility of our approach to recover 3D scenes using eye reflections.
