The two-volume set LNCS 7066 and LNCS 7067 constitutes the proceedings of the Second International Visual Informatics Conference, IVIC 2011, held in Selangor, Malaysia, during November 9-11, 2011. The 71 revised papers presented were carefully reviewed and selected for inclusion in these proceedings. They are organized in topical sections named computer vision and simulation; virtual image processing and engineering; visual computing; and visualisation and social computing. In addition the first volume contains two keynote speeches in full paper length, and one keynote abstract.

This proceedings volume includes papers presented at DGCI 2003 in Naples, Italy, November 19-21, 2003. DGCI 2003 was the 11th conference in a series of internationalconferencesonDiscreteGeometryforComputerImagery.Thec- ference was organized by the Italian Institute for Philosophical Studies, Naples and the Institute of Cybernetics "E. Caianiello," National Research Council of Italy, Pozzuoli (Naples). DGCI 2003 was sponsored by the International Asso- ation for Pattern Recognition (IAPR).

Both these factors contribute to the increased international recognition of the conference. The DGCI conferences attract more and more academic and research institutions in di?erent countries. In fact, 68 papers were submitted to DGCI2003.Thecontributionsfocusondiscretegeometryandtopology, surfaces and volumes, morphology, shape representation, and shape analysis. After ca- ful reviewing by an international board of reviewers, 23 papers were selected for oral presentation and 26 for poster presentation. All contributions were sch- uled in plenary sessions. In addition, the program was enriched by three l- tures, presented by internationally well-known invited speakers: Isabelle Bloch (EcoleNationaleSup erieuredesT el ecommunications, France), LonginJanLa- cki(TempleUniversity, USA), andRalphKopperman(CityCollegeofNewYork, USA). In 2002, a technical committee of the IAPR, TC18, was established with the intention to promote interactions and collaboration between researchers wo- ing on discrete geometry. The ?rst TC18 meeting was planned to be held in conjunction with DGCI 2003, to allow the members to discuss the activity of the technical committee. The outcome from this meeting will help the ongoing research and communication for researchers active within the ?eld during the 18 months between the conferences."

This book constitutes the refereed conference proceedings of the 24rd Iberoamerican Congress on Pattern Recognition, CIARP 2019, held in Havana, Cuba, in October 2019. The 70 papers presented were carefully reviewed and selected from 128 submissions. The papers are organized in topical sections named: Data Mining: Natural Language Processing and Text Mining; Image Analysis and Retrieval; Machine Learning and Neural Networks; Mathematical Theory of Pattern Recognition; Pattern Recognition and Applications; Signals Analysis and Processing; Speech Recognition; Video Analysis.

This book constitutes the refereed post-conference proceedings of the 21st Iberoamerican Congress on Pattern Recognition, CIARP 2016, held in Lima, Peru, in November 2016. The 69 papers presented were carefully reviewed and selected from 131 submissions. The papers feature research results in the areas of pattern recognition, biometrics, image processing, computer vision, speech recognition, and remote sensing. They constitute theoretical as well as applied contributions in many fields related to the main topics of the conference.
