3D Shape from Anisotropic Diffusion
We cast the problem of inferring the 3D shape of a scene from a collection of defocused images in the framework of anisotropic diffusion. We propose a novel algorithm that can estimate the shape of a scene by inferring the diffusion coefficient of a heat equation. The method is optimal, as we pose it as the minimization of a certain cost functional based on the input images, and fast. Furthermo...
متن کاملFlow-rate fluctuations in the outpouring of grains from a two-dimensional silo.
We present experimental results obtained with a two-dimensional silo discharging under gravity through an orifice at the flat bottom. High-speed measurements provide enough time resolution to detect every single bead that goes out and this allows the measurement of the flow rate in short-time windows. Two different regimes are clearly distinguished: one for large orifices, which can be describe...
متن کاملWall Effect in 3D Simulation Of Same Sized Particles Packing
In this paper, the effects of container size on the porosity of random loose packing of mono size particles have been investigated using an Event Dynamics (ED) based model. Simultaneous effects of square container walls on particles packing and their order are also investigated. Our simulation results indicate higher container size will increase the total packing factor and high density regions...
متن کاملFluctuations of grains inside a discharging two-dimensional silo.
We present experimental data corresponding to a two-dimensional dense granular flow, namely, the gravity-driven discharge of grains from a small opening in a silo. We study the local velocity field at the scale of single grains at different places with the help of particle-tracking techniques. From these data, the velocity profiles can be obtained and the validity of some long-standing approach...
متن کاملGrain Size and Shape of Sand Grains in Ergs of Iran
Large areas of Iran are under the influence of wind erosion thus it is important that we recognize three zones ofremoval, transportation and deposition. The deposition zone is very important due to more damages and tangibleeffects. In this study we try to obtain a comprehensive idea to Persian desert with use of laboratory facilities, remotesensing, GIS and field surveying. We survey 28 ergs in...
