Rain removal from a video is a challenging problem and has been recently investigated extensively. Nevertheless, the problem of rain removal from a single image was rarely studied in the literature, where no temporal information among successive images can be exploited, making the problem very challenging. In this paper, we propose a single-imagebased rain removal framework via properly formula...

This effort continues a study of the effects of rain, over the oceans, on the signal retrieved by the SeaWinds scatterometer. It is determined that the backscatter radar cross section can be used to estimate the volumetric rain rate, averaged horizontally, across the surface resolution cells of the scatterometer. The dual polarization of the radar has a key role in developing this capability. T...

This paper presents a method to estimate optical flow under rainy scenes. Optical flow estimation in the rainy scenes is considered challenging due to background degradation introduced by rain streaks and rain accumulation effects in the scene. Rain accumulation effect refers to poor visibility of remote object due to the intense rainfall. Most existing optical flow methods are erroneous when a...

Brightness temperatures at 22.234, 23.834 and 30 GHz and corresponding rain rates were measured using a ground based radiometer and a fast response optical rain gauge co-located with the radiometer during the year 2009 at Cauchuria, Paulista (22.57 0 S, 89 0 W), Brazil. A statistical analysis reveals that the number of occurrences goes beyond 200 times for rain rate up to 15 mm/hr. It was obser...

The Advanced Scatterometer (ASCAT) onboard the Metop satellite series is designed to measure the ocean surface wind vectors globally. Generally, ASCAT provides wind products at excellent quality. The quality of the Advanced Scatterometer (ASCAT) derived winds is known to be generally degraded with increasing values of the inversion residual or maximum likelihood estimator (MLE). In the current ...

INTRODUCTION During 2005, Hurricanes Katrina and Rita struck the US Gulf Coast, displacing approximately two million people. With >250,000 evacuees in shelters, volunteers from the American Red Cross (ARC) and other nongovernmental and faith-based organizations provided services. The objective of this study was to evaluate the composition, pre-deployment training, and recognition of scenarios w...

In the aftermath of a nuclear attack, shelters can offer potentially important protection. How well they fill that role depends on a set of interdependent decisions made by the individuals and organizations that must prepare and use them. We look at three such decisions. For each, we begin with formal analysis of the consequences expected from different possible actions. Those analyses are, the...
