Abstract

We study the motion estimation across three images by simultaneously enforcing the geometric constraint of trilinearity and the constant-brightness constraint. An iterative and hierarchical three-frame scheme is proposed to solve the geometry-consistent and appearance-consistent motion fields. It provides an uncalibrated approach to dense motion estimation, applicable to both 2D and 3D rigid scenes under perspective projection with unconstrained camera motion. Valid and consistent constraints are explored to alleviate the inherent aperture and over smoothing problems
