As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

The SeaWinds on QuikScat and ERS-1/2 scatterometers measure the radar response of the Earth’s surface with high spatialand temporal-resolution. The data collected by these space-borne active-microwave sensors are used to detect periods of surface melting in the Antarctic iceshelves. A description of a statistical melt-detection algorithm is given and the results are shown and compared to other ...

A series of high temperature experiments was undertaken to study partitioning of several highly siderophile elements (HSE; Ru, Rh, Pd, Re, Os, Ir, Pt and Au) between Cr-rich spinel, olivine, pyroxene and silicate melt. Runs were carried out on a Hawaiian ankaramite, a synthetic eucrite basalt, and a DiAn eutectic melt, at one bar, 19 kbar, and 20 kbar, respectively, in the temperature range of ...

The dynamics of the Greenland Ice Sheet are affected by surface meltwater reaching base ice, altering ice contact with bedrock. Lack understanding this evolution hampers ability to predict effects increasing temperatures on mass balance. Here we present a unique high-resolution study velocity response melting based data from COSMO-SkyMed satellite campaign over Upernavik Isstrøm (Northwest Gree...

This paper presents, a hybrid method, low-resolution and high-resolution, for Persian page segmentation. In the low-resolution page segmentation, a pyramidal image structure is constructed for multiscale analysis and segments document image to a set of regions. By high-resolution page segmentation, by connected components analysis, each region is segmented to homogeneous regions and identifyi...
