Automatic segmentation is performed using watersheds of the gradient magnitude and compression techniques. Linear Scale-Space is used to discover the neighbourhood structure and catchment basins are locally merged with Minimum Description Length. The algorithm can form a basis for a large range of automatic segmentation algorithms based on watersheds, scale-spaces, and compression.

an analytical model for a coastal boundary current was used to investigate heat and salt budget of exchange flows in the persian gulf as a marginal sea. coastal boundary currents exchange heat and freshwater with the mosphere and the offshore waters. as heat and salinity fluxes caused by air-sea interaction and eddy activities, different temperature and salinity associated with boundary current...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The National Institute of Standards and Technology (NIST) interferometer for measuring graduated length scales has been in use since 1965. It was developed in response to the redefinition of the meter in 1960 from the prototype platinum-iridium bar to the wavelength of light. The history of the interferometer is recalle...
