The 20 full papers presented were carefully reviewed and selected from 23 submissions. The papers are grouped into two sections. The first one includes twelve papers devoted to theoretical foundations of combinatorial image analysis, including digital geometry and topology, array grammars, picture languages, digital tomography, and other technical tools for image analysis. The second part includes eight papers presenting application-driven research on topics such as image repairing, annotation of images, image reconstruction, forgery detection, and dealing with noise in images Notes International conference proceedings Includes author index Subject Image analysis -- Congresses Combinatorial analysis -- Congresses Image processing -- Digital techniques -- Congresses Combinatorial analysis Image analysis Image processing -- Digital techniques Genre/Form Electronic books proceedings (reports) Conference papers and proceedings Conference papers and proceedings.
