Detecting objects in images is of widespread interest due to a large number of applications in diverse disciplines, including remote sensing, medical images, geology and civil infrastructure. This paper presents a comparison of selected techniques that may be useful for the object detection connected with ground deformations within large areas using satellite radar interferometry (DInSAR, Differential Interferometry Synthetic Aperture Radar) techniques. The DInSAR method, that exploits two SAR images, derives information about ground deformations that occurred between the time of the two SAR data acquisitions. Using this method the ground deformations can be monitored for large areas with high accuracy and very good spatial and temporal resolutions. The results of DInSAR analysis can be used for areas highly endangered by subsidence phenomenon identification. The problem of detecting objects in the images is very challenging due to many reasons, e.g. speckle, the presence of incomplete and distorted parts of objects, corruption in the quality of edges or lack of a priori information. The main purpose of this paper was to present and compare methods that can be used at various stages of SAR images analysis, such as preprocessing (filtration, noise reduction, edge detection) or object detection (detection of specific objects or shapes).
