This book constitutes the refereed proceedings of the 15th IAPR International Conference on
Discrete Geometry for Computer Imagery DGCI 2009 held in Montréal Canada in September
October 2009. The 42 revised full papers were carefully reviewed and selected from numerous
submissions. The papers are organized in topical sections on discrete shape representation
recognition and analysis discrete and combinatorial tools for image segmentation and analysis
discrete and combinatorial Topology models for discrete geometry geometric transforms and
discrete tomography.
