摘要：Disaster management has got an important facet, viz., disaster mitigation, which in turn depends upon early damage assessment. Remote Sensing is considered as an ideal technique for obtaining early information. This exercise has been carried out for assessing the damaged area, automatically, based on high-resolution post-earthquake images in Gujarat, India and high resolution satellite images of tsunami-affected areas in India and Sri Lanka. The damaged area in the form of rubble manifested as fine structure in the image. The separation of the fine structure from the rest of the image is attempted by scale-space representation approach. This method is found to be very effective for estimation of damaged area automatically in quick time and can be a very useful tool in the disaster management
