Current state of the art computational fluid dynamics (CFD) and in particular, river flow modelling, require accurate estimation of the " free surface " in order to accurately predict the three dimensional flow field along a river. Such models are increasingly important for management of river basins and mitigation of river floods as the incidence of(More)
—This paper presents a new edge detection algorithm based on calculating the difference value of two clusters. An edge is defined as a boundary that separates two adjacent regions that are relatively homogenous. For each image pixel, a window is first defined by placing the pixel at the center, and this window is partitioned into two sub-regions(More)
