This paper exposes an algorithm which leads to a fuzzy segmentation. This algorithm performs, as in the watershed method, a progressive flood of the gradient image from pixels of lowest gradients. It uses a new distance, called topographic distance. Any local minimum of the gradient norm image constitutes a seed for the region growing, avoiding the use of a marker image. These seeds constitute ...

Surat faced the most devastating flood on 7 August 2006. This flood preceded by heavy rains in the catchment areas of Ukai Dam, and consequent massive releases of water from the dam from 6 August through 11 August 2006, inundated the city, and slums were the worst hit. Studies have reported increased mosquito breeding and epidemics of malaria as an aftermath of floods in Mandla1, subsequent to ...

Mars Orbiter Camera (MOC) images and Mars Orbiter Laser Altimeter (MOLA) data on the Mars Global Surveyor (MGS) spacecraft show evidence for three catastrophic outflow channels around the Cerberus Plains region, Mars. The morphologies seen in MOC images located within channels seen in gridded MOLA topography are similar to those found in catastrophic flood terrains on Earth, such as the Channel...

Introduction: Regional topography, volcanic and tectonic patterns, and gravity signatures (the latter not yet available for Io) are the primary manifestations of a planets internal dynamics [1,2]. This report is motivated by several new developments, the most important of which are significant upgrades to our stereo topographic mapping capabilities and the successful application of shape-from-s...

This paper discusses the challenges in designing public boating infrastructure vast tidal flood plains, including different construction techniques used, lessons learned design and how they have been adapted other projects. The case study focuses on two recreational projects at Inkerman Creek Casuarina Creek, located plain delta of Fitzroy River Central Queensland region.
