Rotation, Scale and Translation invariant image retrieval method based on Circular Segmentation and Color Density

Pierre-André Farine, Sara Grassi Pauletti, Pradyumna Ayyalasomayajula

We propose a fast and efficient method for Content Based Image Retrieval (CBIR) which uses color densities within concentric circular zones of the image, encompassing edge-pixels. This method is invariant to Rotation, Scale and Translation (RST). Small-siz ...

On the proportion of upward flashes to lightning research towers

Marcos Rubinstein, Wolfgang Schulz

We compare in this paper direct measurements obtained at the Towers on Mount San Salvatore (Switzerland) and the Gaisberg Tower (Austria). They are situated in similar topographical environments but in different lightning activity zones. Direct measurement ...

“Slow Light” in stimulated Brillouin scattering: on the influence of the spectral width of pump radiation on the group index: Comment

Luc Thévenaz

In a recent paper by Kovalev et al [Optics Express 17, 17317 (2009)] the coupled equations describing stimulated Brillouin scattering (SBS) were solved in the Fourier domain. The main conclusion driven by the authors was that SBS pump spectral broadening w ...
