Multiple Illuminant Direction Detection with Application to Image Synthesis
TLDR
We introduce the concept of critical points, where the surface normal is perpendicular to some light source direction, to determine light source directions and their intensities if certain conditions are satisfied. Expand

Tri-focal tensor-based multiple video synchronization with subframe optimization
TLDR
In this paper, we present a novel method for synchronizing multiple (more than two) uncalibrated video sequences recording the same event by free-moving full-perspective cameras. Expand
