Subpixel Resolution Schemes for Multiphase Flows
This effort explores novel sub-resolution particle center estimation algorithms for Digital Particle Tracking Velocimetry (DPIV). The errors of these new methods were classified through Monte-Carlo simulations. These schemes provide direct measurements of the apparent particle image diameter and …

A three dimensional vision system for industrial surface topography measurement
… and processed so that, in certain cases, subpixel resolution of the centre of the laser spot can be obtained. Expansion of the laser spot and varying the parameters of the optical system are examined to assess their effect over different target materials and estimates of the possible range …

Volcanology from space: applications of infrared remote sensing
… are used to constrain sizes and temperatures of subpixel resolution hot spots. Analysis of a 1989 TM scene of Lonquimay volcano suggests a cooling from 250 to 170°C of the crust of an active lava flow down 1.5 km of its length. Estimates of the summed radiative and convective heat losses from the …
