Optimal rates of convergence for convex set estimation from support functions

A Guntuboyina - The Annals of Statistics, 2012 - JSTOR
We present a minimax optimal solution to the problem of estimating a compact, convex set
from finitely many noisy measurements of its support function. The solution is based on …

High-Precision registration of point clouds based on sphere feature constraints

J Huang, Z Wang, J Gao, Y Huang, DP Towers - Sensors, 2016 - mdpi.com
Point cloud registration is a key process in multi-view 3D measurements. Its precision affects
the measurement precision directly. However, in the case of the point clouds with non …
