Abstract :
This paper presents a new method to detect the road in synthetic aperture radar (SAR) images based on B-spline wavelet. In this method, B-spline wavelet is constructed firstly. The roads can be detected by searching the maximal amplitude of the SAR images´ wavelet transform. In order to alleviate the influence of the speckle of SAR image, an idea of mean was introduced into this algorithm. Experiment results shows that the algorithm is very effective and superior to other classical edge detection operators.
