An automatic method for detecting and interpreting bridges over water in TerraSAR-X imagery is proposed.Two kinds of image textures including the Gabor features and graylevel co-occurrence matrix statistics are employed to segment the image in multiple scales and obtain the regions of interest(ROIs)of bridge.Line segment detector is used to estimate the direction of bridge.For each ROI,five key parameters of a bridge are estimated based on the imaging model of radar, including angle,width,elevation over wat...
