                         black and white source image, the proposed method outputs the 
                         geometry of all individual stones that compose the pavement. 
                         Different from previous mosaic techniques, we focus on capturing 
                         the particularities of such pavements: the stones (tiles) must 
                         completely follow the edges, being mostly represented by irregular 
                         quadrilaterals with no particular orientation. A set of
