Enhancement Of Satellite Image Resolution With Moving Objects
Satellite images are being used in many applications like Meteorology, Agriculture, Geology, Forestry, Landscape, Biodiversity, Planning, Education, Regional, Seismology and oceanography. The Enhanced satellite images make diagnostic details more obvious. The Image Enhancement is the main technique for improving the resolution and visual appearance of the image. One of the major issues in Image...

متن کاملPyroclastic Flow Simulation by a Cellular Automata Model
We developed a minimal three-dimensional Cellular Automata (CA) model for pyroclastic flows, generated by collapsing volcanic columns. Our aim is to simulate numerically simple ideal situations and to test that main phenomenological conditions appear correctly in the simulations. Model applications could be very important in order to assess pyroclastic flow hazard in densely inhabited areas. CA...
متن کاملDetection of Coastline Using Satellite Image-Processing Technique
Extended abstract 1- Introduction Coasts maintain their natural sustainability without human intervention and in spite of short-term changes, we are ultimately confronted with a coastal healthy environment, i.e. natural, rocky beaches, sandy beaches and so on. Today's use of remote sensing in most natural sciences is widespread. Due to the fact that fieldwork is costly and time-consuming, ...
متن کاملSources of Unsteady Column Dynamics in Pyroclastic Flow Eruptions
During the first several minutes of an explosive volcanic eruption, the flow in the column above the vent is unsteady even if the discharge from the vent is steady. At a fixed location in the column, parameters such as temperature and ash content change with time until steady flow conditions are established. For conditions believed to be typical of fountain-forming silicic eruptions of intermed...
