Comparison of Prefiltering Operators for Road Network Extraction in Sar Images
In thispapel; the problem of the detectionof road networks in Synthetic Aperture Radar (SAR) images is addressed. This task is importantfor the registration ofSAR images to existing maps and for perfect superposition of multitemporal SAR images. SAR image analysis is a dificult task because of speckle noise and textures and low Signal to Noise Ratios. Thispaperfocuses on the comparison ofjilter performances in terms of road extraction. Thisstudy points out the interest of nonlinear adaptive jiltering techniques. On the other hand, it is shown that techniques dedicated to speckle noise jiltering are not always the most suited to road network extraction.
