This paper presents a novel method for online real-time content-based image training and retrieval. The method relies on bags-of-words with SIFT features, and data can be extracted from a generated large scale vocabulary tree to describe all kind of images. The large-scale vocabulary tree can be seen as a code book that new images can be described. We use a large-scale vocabulary tree to generate...
Digital Elevation Model is one of the most important fundamental geographical datasets in National Spatial Data Infrastructure (NSDI). How to improve the accuracy and applicability of existing contour based DEM is one of key issues in DEM updating. Existing approaches mostly by the new technique which need more financial support. This paper presents a DEM oriented correction strategy that directly...
An important task in hyperspectral data processing is to reduce the redundancy of the spectral and spatial information without losing any valuable details that are needed for the subsequent detection, discrimination and classification processes. Band selection and combination not only serves as the first step of hyperspectral data processing that leads to a significant reduction of computational complexity,...
