Sažetak
Clusters are grid basic elements consisted of the independent computers working as one unique computer for realization of greater computer power. They are often used for execution of demanding scientific and technological calculations. The CRO-GRID is national grid, composed of five connected geographically distanced clusters. ETFOS Cluster is one of the CRO-GRID's clusters. It is Beowulf type of cluster with one central node. In this work it is used for processing of RGB images of ceramic tiles. The pictures are converted into binary pictures using global threshold. We determine border of an object in the picture, starting by determining the size of the object. In order to determine the size, we look for the most prominent pixel on the every picture side: left, right, up and down. After this, every edge is divided on the given number of segments and we look for marginal pixel of every segment. Values of marginal pixels are saved in vectors in order to analyze the orientation of pictures. The processing is performed on personal computer and on the cluster for comparison of necessary processing run times.
