Correction of line drawings for image segmentation in leather industry

Gives a brief description of the operation principles of LeaVis, a prototype industrial machine vision system aimed at processing and segmentation of the images of hides marked by lines and other symbols that show defects and areas of different quality. A key feature of the vision system is its ability to correct line drawings by connecting broken lines and bridging gaps in line junctions. The goal of LeaVis is to provide a coherent visual input for a computer aided layout design system that creates trajectory descriptions by which the knife cutting the hides is controlled. The authors discuss the basic motivations of the vision system design, and present the ideas behind its core algorithms
