It is indeed a great pleasure to welcome you to the proceedings of the 12th International Workshop on Combinatorial Image Analysis (IWCIA 2008) held in Bu?alo NY April 7-9 2008. Image analysis is a scienti?c discipline providing theoretical foundations and methods for solving problems that appear in various areas of human practice as diverseas medicineroboticsdefenseandsecurity.As a rulethe processeddata are discrete; thus the "discrete" or "combinatorial"approachto image analysis appears to be a natural one and therefore its importance is increasing. In fact combinatorial image analysis often provides various advantages (in terms of - ciency and accuracy) over the more traditional approaches based on continuous models requiring numeric computation. The IWCIA workshop series provides a forum for researchers throughout the world to present cutting-edge results in combinatorial image analysis to discuss recent advances in this research ?eld and to promote interaction with researchersfromothercountries.InfactIWCIA2008retainedandevenenriched the international spirit of these workshops that had successful prior meetings in Paris (France) 1991 Ube (Japan) 1992 Washington DC (USA) 1994 Lyon (France) 1995 Hiroshima (Japan) 1997 Madras (India) 1999 Caen (France) 2000 Philadelphia (USA) 2001 Palermo (Italy) 2003 Auckland (New Zealand) 2004 and Berlin (Germany) 2006.The IWCIA 2008 Program Committee was highly international as its members are renowned experts coming from 23 di?- entcountriesandsubmissionscamefrom24countriesfromAfricaAsiaEurope North and South America.
