Variational solutions to simultaneous collisions between multiple rigid bodies
— We present a method of resolving simultaneous collisions between multiple rigid bodies based on the least action principle. By using the generalized directional derivative of t...

Efficient Reduction of L-infinity Geometry Problems
This paper presents a new method for computing optimal L1 solutions for vision geometry problems, particularly for those problems of fixed-dimension and of large-scale. Our strat...

Nonlinear and Nonideal Sampling: Theory and Methods
We study a sampling setup where a continuous-time signal is mapped by a memoryless, invertible and nonlinear transformation, and then sampled in a nonideal manner. Such scenarios a...

Efficient Camera Smoothing in Sequential Structure-from-Motion Using Approximate Cross-Validation
Abstract. In the sequential approach to three-dimensional reconstruction, adding prior knowledge about camera pose improves reconstruction accuracy. We add a smoothing penalty on t...
