An algorithm for SAR images based on knowledge of bridge over water is proposed. According to the positional relationship between bridge and river, it is pivotal for recognition to extract river correctly. First, pretreatment for SAR images is necessary, including noise reduction and image enhancement. Second, region-based threshold segmentation, region growing and mathematical morphology are used...
Target recognition is an important field in remote sensing image processing. This paper handles with the problem of bridge recognition in Synthetic Aperture Radar (SAR) images. Based on features of bridges, rivers and land in different spatial resolution SAR images, a method of multi-scale analysis is proposed. The original data is split into low and middle resolution level. The bridge candidates...
