Reflectance pattern and spatial pattern characterize the geospatial data. Current semantic-enabled framework retrieval system extract primitive features based on color, texture (Spatial Gray Level Dependency - SGLD matrices), and shape from the segmented homogenous region. This system can use only three bands (true color or false color) at a time to capture color information as it converts RGB space...
These level ice charts are automatically derived from man- made ice thickness charts using novel SAR information [1]. The aim of the present study has been to include some navigationally meaningful information about the degree of ice deformation into these level ice thickness charts. To this end, we propose a procedure where the SAR image is first segmented, and then an ice thickness distribution...
Video image matching to find tie points is one of important steps for merging dynamic, narrow field-of-view aerial video into a mosaic orthoimage. Because of its high data sampling rates and inherent characteristics of inconsistent and unstable flying of low-cost unmanned aerial vehicle (UAV), automatically matching of video data is still a big challenge and ongoing effort. This paper presents a self-adaptive...
