This book constitutes the refereed proceedings of the 6th International Conference on Games and Learning Alliance, GALA 2017, held in Lisbon, Portugal, in December 2017. The 16 revised regular papers presented together with 6 poster papers were carefully reviewed and selected from 45 submissions. The papers cover topics such as games in education and training; games for health and special children; augmented and virtual reality; methods and tools (for desing and development); and poster abstracts.

Images and video play a crucial role in visual information systems and multimedia. There is an extraordinary number of applications of such systems in entertainment, business, art, engineering, and science. Such applications often involved large image and video collections, and therefore, searching for images and video in large collections is becoming an important operation. Because of the size of such databases, efficiency is crucial. We strongly believe that image and video retrieval need an integrated approach from fields such as image processing, shape processing, perception, database indexing, visualization, and querying, etc. This book contains a selection of results that was presented at the Dagstuhl Seminar on Content-Based Image and Video Retrieval, in December 1999. The purpose of this seminar was to bring together people from the various fields, in order to promote information exchange and interaction among researchers who are interested in various aspects of accessing the content of image and video data. The book provides an overview of the state of the art in content-based image and video retrieval. The topics covered by the chapters are integrated system aspects, as well as techniques from image processing, computer vision, multimedia, databases, graphics, signal processing, and information theory. The book will be of interest to researchers and professionals in the fields of multimedia, visual information (database) systems, computer vision, and information retrieval.

The papers in this volume are a good sampling and overview of current solutions to the problems of creating graphically based systems. This breadth of scope comes out of the closing discussion at the Fourth Eurographics Workshop on Object-Oriented Graphics. The fifth workshop, on Programming Paradigms in Graphics, set out to provide answers and alternatives to the shortcomings of object-oriented graphics. The presentations investigated the applicability, merits and problems of various programming paradigms in computer graphics for design, modelling and implementation. This book contains a revised selection of the best papers from the Fifth Eurograph ics Workshop on Programming Paradigms in Graphics, held 2-3 September 1995 in Maastricht, The etherlands. All papers at the workshop were subjected to a thorough review by at least three members of the international programme committee. The se lection for this book was based on further review and the papers also incorporate the relevant aspects of the discussions at the workshop. In past Eurographics workshops on Object-Oriented Graphics the prominent trend has been a discovery of the limits of object-orientation in graphics. The limitations of object-orientation were felt to lie in such areas as the expression of relationships between objects. This is an area of particular strength for the declarative languages, such as constraint-based languages. On the other hand, a notion of state has long been a problem in declarative languages and yet it is often seen as an essential aspect of graphical modelling, particularly in simulation and animation."

This monograph is devoted to computational morphology, particularly to the construction of a two-dimensional or a three-dimensional closed object boundary through a set of points in arbitrary position.
By applying techniques from computational geometry and CAGD, new results are developed in four stages of the construction process: (a) the gamma-neighborhood graph for describing the structure of a set of points; (b) an algorithm for constructing a polygonal or polyhedral boundary (based on (a)); (c) the flintstone scheme as a hierarchy for polygonal and polyhedral approximation and localization; (d) and a Bezier-triangle based scheme for the construction of a smooth piecewise cubic boundary.

This book constitutes the refereed proceedings of the 5th International Conference on Games and Learning Alliance, GALA 2016, held in Utrecht, The Netherlands, in December 2016. The 27 revised regular papers presented together with 14 poster papers were carefully reviewed and selected from 55 submissions. The papers cover topics such as games and sustainability; games for math and programming; games and health; games and soft skills; games and management; games and learning; game development and assessment; and mobile games.
