Automated intensity-based image registration approaches become popular and urgent when facing today's increasing data mining and frequent fusion demands. As a core part of an automated image registration system, many kinds of gradient-based optimizers were proposed in the past decade. In this paper, a local gradient-free optimizer, namely the simultaneous perturbation stochastic approximation (SPSA)...
A method for detecting clutter in weather radar images by information fusion is presented. Radar data, satellite images, and output from a numerical weather prediction model are combined and the radar echoes are classified using supervised classification. The presented method uses indirect information on precipitation in the atmosphere from Meteosat-8 multispectral images and near-surface temperature...
Monitoring of tobacco planted acreage is a very important step for tobacco's management and monitoring. The paper presents a monitoring method by data fusion of multiple remote sensing sources. It extracts tobacco areas according to the NDVI value and classifies the fusion image with texture information, then classifies the SAR data to acquire tobacco plot in cloudy area. After classification post-processing...
