Asinthepreviouseditions,theconferenceattractedresearchersfromdifferent countries attesting the international relevance of the event. After an accurate reviewing process that, from this edition, supported the decisions with a final rebuttal phase, 34 papers were accepted, out of about 60 submissions. The22papersscheduledinasingle-trackoforalpresentationswereorganized intopicalsectionsonModelsforDiscreteGeometry;DiscreteandCombinatorial Topology; Geometric Transforms; Discrete Shape Representation, Recognition andAnalysis;Discrete Tomography;MorphologicalAnalysis; DiscreteModeling and Visualization; Discrete and Combinatorial Tools for Image Segmentation and Analysis. The remaining 12 papers on these same topics were grouped into a single poster session. As in the previous two editions, the conference included a demonstration session, in the intent ofproviding the opportunity to presentandshare effective applications, new tools, and libraries related to the mainstream of the image processing. Three internationally well-known researchers provided invited lectures: Pro- fessorPeterGritzmann,fromTechnischeUniversita¨tofMu¨nchen,Germany,Pro- fessor Lorenzo Robbiano from the University of Genova, Italy, and Professor Marco Gori, from the Univerity of Siena, Italy. DGCI2014wassupportedbytheInternationalAssociationofPatternRecog- nition (IAPR), and constituted the main event associated with the Technical Committee on Discrete Geometry IAPR-TC18. Wewouldliketothankthemainsponsoringinstitutions:theDipartimentodi Matematica ed Informatica of the University of Firenze, and the Dipartimento diIngegneriadell’InformazioneeScienzeMatematicheoftheUniversityofSiena who also hosted the conference and provided all the necessary facilities. We aregratefulto the members ofthe SteeringCommittee fortheir valuable supportandtheinspiringdiscussions,withaspecialmentiontoDavidCoeurjolly who helped us through all the steps of the reviewing process. Specialthankstotheauthorsofthesubmittedcontributionswhoseresearches confirmedthe high level standardof the conference, to the ProgramCommittee VI Preface and all the reviewers for their accurate and proficient work, to the local Orga- nizing Committee for its tireless support, and to all the participants attending the conference, who contributed to make this event a success.
