This paper presented incremental support vector data description (ISVDD) method and used it to detect anomalies in hyperspectral images. Anomaly detection is essentially a problem of one-class classification, a good solution of which is SVDD, using optimized minimal hypersphere to express tightly the background and using distinguish function to detect anomalous pixels. The method avoided the problem...
The 0908 typhoon “Morakot” heavily attacked Taiwan. It brought strong rainfall which not only caused water level rise in several reservoirs and rivers, but also triggered a large number of landslides, debris flow, collapse and other geological disasters. In this paper, using NDVI(Normal Differential Vegetation Index) subtractive method, together with band combination symbol coding method, “Morakot”...
Soil moisture is a highly variable component of soil, and plays an important role in materials and energy exchanges between earth and atmosphere. It is also the basic parameter of crop growing and crop yield forecast. With the features of observing large area synchronously, timely, and economically, remote sensing technique makes dynamic soil moisture monitoring possible. Soil moisture remote sensing...
