In order to prepare minimal feature vectors to be used in a Content Based Image Recognition (CBIR) system, we are proposing methods that can accurately identify the main colors contained in a digital image. The methods use the “LAB” color space properties that allow for all the colors of the same intensity or luminance “L” to be placed uniformly in the same “ab” plane. Basically, RGB images are first preprocessed: trimmed, scaled and transformed in the LAB color space. Then (a,b) pairs, corresponding t...

Floods are river basin wide phenomena and they often create common problems with locally varying intensity. The flood disaster management is highly dependent on early information and needs forecasts and data from the river basin as a whole. The starting point for flood risk management planning is the assessment of flood risks, based on the information about the river basin and floods in the past. The next step is developing strategies for reaction when flooding events are prognosticated, and evaluation of these st...

This paper presents an algorithm for construction of a patch from a set of points in 3D space. Usualy, such set of points is a subset of surface points obtained from, for example, a 3D model or a terrain. To construct the patch, the points should be connected into a triangular mesh. Because the patch can have various characteristics the connection of input points in the resulting triangular mesh is rather difficult. The algorithm starts with construction of a 3D convex hull from given set of points. The 3D convex ...
