Based on multi-scale joint segmentation method,a SAR image changing detection algorithm over power corridor area is proposed in this paper.Firstly,through TurboPixels algorithm,multi-scale joint over-segmentation for multi-temporal SAR images over power corridor area is conducted.Each segment is considered as a super-pixel.Then,the difference map based on the statistical distribution differences of super-pixel pairs is calculated.Finally,the final changed regions from the difference map are extracted by using an automatic threshold method.Experimental results show that the algorithm has a better changing detection performance.
