Texture-Based Segmentation of Satellite Weather Imagery
Unsupervised segmentation of weather images into features that correspond to physical storms is a fundamental and difficult problem. Treating an infrared satellite image as a Markov random field, the Kolmogorov-Smirnov distance between the local distribution of spatial statistics and the global statistics of classified regions is used to segment the image using a relaxation algorithm. An outlie...
متن کاملSatellite Weather Information and Intelligent Transportation System
Photo courtesy of the California Department of Transportation On her way to pick up her daughter from King Magnet Elementary at Downtown Little Rock, Amy notices the dark clouds of a thunderstorm rapidly approaching. Meanwhile computers at a private meteorological service is using data from the National Weather Services and the Arkansas Department of Transportation to produce a highly specific ...
متن کاملCloudy forecast for weather satellite data.
IN THE NEWS FOCUS STORY “WEATHER forecasts slowly clearing up” (9 November, p. 734), R. Kerr nicely summarizes how the growing improvement in prediction is coming from a focus on “more computer power, the assimilation of radar observations, and more physically realistic models.” He emphasizes that better assimilation of satellite data is a key element of improved forecasting. Unfortunately, the...
متن کاملTrajectory Simulations , Qualitative Analyses and Parametric Studies of A Laser - Launched Micro - Satellite Using OTIS ( Preprint
This paper will discuss Air Force Research Laboratory (AFRL) Propulsion Directorate’s theoretical and computational results regarding trajectory simulations, qualitative analyses and parametric studies of a 25-cm focal diameter Laser Ramjet (X-25LR) using Optimal Trajectories by Implicit Simulation (OTIS). OTIS has been used to produce an optimized trajectory simulation of a laser ramjet’s flig...
متن کاملHierarchical Texture Segmentation of Weather Radar and Satellite Images
Segmentation of weather imagery is a problem fundamental to automated weather analysis, but one that has defied good solutions. Weather images have certain characteristics that cause problems for traditional image processing algorithms – the textural nature of clouds, poor dynamic range and poor spatial resolution. In this paper, we describe a novel method of performing multiscale, hierarchical...
