Although digital geometry has its roots in several classical disciplines (such as graph theory, topology, number theory, and Euclidean and analytic geometry), it was established as an independent subject only in the last few decades. Several researchers have played a pioneering role in setting the foundations of digital ge- ometry. Notable among these is the late Azriel Rosenfeld and his seminal works fromthelate60’sandearly70’softhelastcentury.Someauthorsofchaptersofthe present book are also among the founders of the area or its prominent promoters. Thelasttwodecadesfeatureanincreasingnumberofactivecontributorsthroughout theworld.Anumberofexcellentmonographsandhundredsofresearchpapershave beendevotedtothesubject.Onecanlegitimatelysaythatatpresentdigitalgeom- etry is an independent subject with its own history, vibrant international commu- nity,regularscientificmeetingsandevents,and,mostimportantly,seriousscientific achievements. This contributed book contains thirteen chapters devoted to different (although interrelated)importantproblemsofdigitalgeometry,algorithmsfortheirsolution, and various applications. All authors are well-recognized researchers, as some of themareworldleadersinthefield.Asageneralframework,eachchapterpresents a research topic of considerable importance, provides a review of fundamental re- sultsandalgorithmsfortheconsideredproblems,presentsnewunpublishedresults, aswellasa discussiononrelatedapplications,currentdevelopmentsandperspec- tives.Byitsstructureandcontent,thispublicationdoesnotappeartobeanexhaus- tivesourceofinformationforallbranchesofdigitalgeometry.Rather,thebookis aimed at attracting readers’ attention to central digital geometry tasks and related v vi Preface applications,asdiverseascreatingimage-basedmetrology,proposingnewtoolsfor processing multidimensional images, studying topological transformations for im- ageprocessing,anddevelopingalgorithmsforshapeanalysis. Anadvantageofthechosencontributedbookframeworkisthatallchapterspro- vide enough complete presentations written by leading experts on the considered specific matters. The chapters are self-contained and can be studied in succession dictatedbythereaders’interestsandpreferences. Webelievethatthispublicationwouldbeausefulsourceofinformationforre- searchers in digital geometry as well as for practitioners in related applied disci- plines. It can also be used as a supplementary material or a text for graduate or upperlevelundergraduatecourses.
