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.

"Eurographics" is a series of workshops, an international forum where researchers convene to exchange knowledge and experience related to the theme of creating realistic computer animation based on the simulation of physical and biological phenomena. The papers in this volume are a sampling and overview of current solutions to the problems of creating graphically-based systems. The presentations investigte the applicability, merits and problems of various programming paradigms in computer graphics for design, modelling and implementation. The papers are grouped into four parts: object-oriented, constraints, functional and multi-paradigm. This essentially takes the reader on a tour of the issues. Firstly, there are the impressive benefits and power of object-oriented approaches, both as, conceptually, tools for design and as programming frameworks. In constraints, though, the limitations are exposed and addressed. Functional programming provides an alternative approach with some recent breakthroughs conceptually (for example, the use of monads to express state) and in practice.Finally, some approaches to resolving (or at least enumerating) the multiplicity of approaches enountered are presented.

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.

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.

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.
