In this paper we show that the move pruning method we presented at SoCS last year sometimes prunes all the least-cost paths from one state to another. We present two examples exhibiting this erroneous behaviour–a simple, artificial example and a slightly more complex example that arose in last year’s experiments. We then formally prove that a simple modification to our move pruning method makes...

We consider homogenization questions related to Maxwell partial differential equations. More precisely, we consider an assembly of particles, viewed as dipoles, separated in a peridioc way with a typical lenght denoted by ". The size of each dipole is denoted by r ". Depending on the relative size of these two scales, we describe the limiting partial differential equations, showing a typical di...

Fourier transform infrared photoacoustic spectroscopy can be used as a nondestructive method to probe the molecular composition of materials as a function of depth into the sample. This is done by varying the thickness of the surface layer being analyzed, which can be as great as some tens of micrometers, depending on optical and thermal properties.Computational methods are described to process...

Satellite retrievals of cloud optical depth and effective radius are shown to be underestimated in the South Atlantic Ocean, where biomass-burning aerosols typically reside above low-level, liquid water stratocumulus clouds. A radiative transfer model is used to calculate top of the atmosphere (TOA) reflectances for a case where an aerosol layer is elevated above a liquid cloud in the South Atl...

We extend the Miles mechanism of wind-wave generation to finite depth. A β-Miles linear growth rate depending on the depth and wind velocity is derived and allows the study of linear growth rates of surface waves from weak to moderate winds in finite depth h. The evolution of β is plotted, for several values of the dispersion parameter kh with k the wave number. For constant depths we find that...

This research features a novel approach that efficiently detects depth edges in real world scenes. Depth edges play a very important role in many computer vision problems because they represent object contours. We strategically project structured light and exploit distortion of the light pattern in the structured light image along depth discontinuities to reliably detect depth edges. Distortion...

Using photographic flash for candid shots often results in an unevenly lit scene, in which objects in the back appear dark. We describe a spatially adaptive photographic flash system, in which the intensity of illumination varies depending on the depth and reflectivity of features in the scene. We adapt to changes in depth using a single-shot method, and to changes in reflectivity using a multi...
