Weighted Sum of Segmented Correlation: An Efficient Method for Spectra Matching in Hyperspectral Images
Sampriti Soor, Priyanka Kumari, B. S. Daya Sagar +1
Matching a target spectrum with known spectra in a spectral library is a common method for material identification in hyperspectral imaging research. Hyperspectral spectra exhibit…

Generation of High Spatial Resolution Terrestrial Surface from Low Spatial Resolution Elevation Contour Maps via Hierarchical Computation of Median Elevation Regions
Geetika Barman, B. S. Daya Sagar
We proposed a simple yet effective morphological approach to convert a sparse Digital Elevation Model (DEM) to a dense Digital Elevation Model. The conversion is similar to that of…
