This book constitutes the refereed proceedings of the 9th International Conference on Discrete Geometry for Computer Imagery, DGCI 2000, held in Uppsala, Sweden in December 2000. carefully reviewed and selected from 62 submissions. surfaces and volumes, shape representation, and shape understanding.

This book constitutes the refereed proceedings of the 11th International Conference on Discrete Geometry for Computer Imagery, DGCI 2003, held in Naples, Italy, in November 2003.The 49 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 68 submissions. All current issues in discrete geometry for computer imagery are addressed including topology, surfaces and volumes, morphology, shape representation, and shape analysis.

This book contains revised and extended versions of selected papers from the 5th International Conference on Pattern Recognition, ICPRAM 2016, held in Rome, Italy, in February 2016.

The 13 full papers were carefully reviewed and selected from 125 initial submissions and describe up-to-date applications of pattern recognition techniques to real-world problems, interdisciplinary research, experimental and/or theoretical studies yielding new insights that advance pattern recognition methods.

This book contains revised and extended versions of selected papers from the 10th and 11thInternational Conference on Pattern Recognition, ICPRAM 2021 and 2022, held in February 2021 and 2022. Due to COVID-19 pandemic the conferences were held virtually. Both conferences received in total 204 submissions from which 8 full papers were carefully reviewed and selected for presentation in this volume. The papers span a wide range of investigation as well as development lines, which of course always reflect the last trends of research in the pattern recognition community.
