Segmentation based change detection in ERS-1 SAR images

Segmentation based change detection in ERS-1 images of agricultural and salt playa scenes is discussed. The segmentation algorithm, RWSEG, is briefly described. The authors primarily concentrate on structural rather than radiometric change. Structural change is analysed by overlaying segment boundaries. This reveals a surprising amount of structural similarity in the image sequences. However, this simplistic approach does not allow for boundaries being slightly offset due to speckle and gradual gradients.<
