Typical applications based on remote sensing imagery start with a visual inspection and selection of scenes and regions of interest to be purchased. In this letter, we propose a so-called Earth observation (EO) epitome as a novel value-added interactive product. Basically, it comprises several image tiles, primitive features, metadata entries, a quick look of the image tiles, and semantic annotations...
In this paper, we present the visualization of image databases based on their primitive features. Our approach is to have a visual navigation tool for allowing the exploration and exploitation of large image archives. The tool is able to project the content of a given image database based on the primitive feature space and to provide interaction between the final user and the huge amount of data....
In this paper, we present a comparative evaluation of two content-based image retrieval systems, the first one based on texture feature extraction methods and machine learning algorithms and the second one based on compression methods and similarity metrics. The evaluation is carried out using high resolution optical and SAR data. The test data set is composed of 4000 tiles, with 64×64 pixel size...
