Resumo
Fernando Soares and Vinicius Barbon, from the Faculty of Sciences of the University of Lisbon, Portugal, present the paper ‘Image segmentation of breakwater blocks by edge-base Hough transformation’. In this work, the authors investigate the problem of detecting block displacements in a rubble mound breakwater, which is critical, for they make harbors more vulnerable to waving hazard. Based on 3D point clouds collected by using synchronized time-of-flight sensors and photogrammetry, this study proposes the use of an edge-based image segmentation method, based on the Hough transformation algorithm. The results demonstrate that the proposed image segmentation methodology improves the monitoring of block displacements in terms of accuracy and also reduces the required analysis time.
