Paper Abstract

In this paper, we propose the use of directional Gabor filtering and multifractal analysis based quality control (QC) to provide accurate identification of precipitation in weather data collected from meteorological-radar volume scans. The QC algorithm is an objective algorithm that minimizes human interaction. The algorithm utilizes both textural and intensity information obtained from the two lower-elevation reflectivity maps. Computer simulations are provided to show the effectiveness of this algorithm.
