Zusammenfassung:Ratio Of Exponentially Weighted Averages (ROEWA) operator is an edge detector suitable for SAR, images. However, the detector can not compute the direction of edges accurately. Due to the excellent directional selectivity of Gabor filters, this paper puts forward a method of utilizing Gabor filter to computer edge direction. And by this way, the edge detector is improved. Experimental results prove that the performance of the improved method is satisfactory.
