Communication Efficient Algorithms for Bounding and Approximating the Empirical Entropy in Distributed Systems Open
The empirical entropy is a key statistical measure of data frequency vectors, enabling one to estimate how diverse the data are. From the computational point of view, it is important to quickly compute, approximate, or bound the entropy. I…

Newton-PnP: Real-time Visual Navigation for Autonomous Toy-Drones Open
The Perspective-n-Point problem aims to estimate the relative pose between a calibrated monocular camera and a known 3D model, by aligning pairs of 2D captured image points to their corresponding 3D points in the model. We suggest an algor…

The Non-Tightness of a Convex Relaxation to Rotation Recovery Open
We study the Perspective-n-Point (PNP) problem, which is fundamental in 3D vision, for the recovery of camera translation and rotation. A common solution applies polynomial sum-of-squares (SOS) relaxation techniques via semidefinite progra…
