From simple to complex - use a compass to draw fascinating artistic images. This book includes step-by-step instructions for all symmetries between threefold and twelvefold. Clear and precise black-and-white illustrations will guide you. The book provides ruler and compass constructions that you can draw without using units of measurement for three-, four-, five-, six-, eight-, ten- and twelvefold symmetries. In addition, it gives dimensions in inches (and cm) for all images, which you can use on both A4 and A3 sheets.

Python for Rookies is designed to help students learn how to program. Using the Python language as a tool, the approach taken teaches students the fundamentals of programming and re-enforces good programming practice. Written for students studying a variety of degree subjects such as Games Technology, Creative Computing and Multimedia (where core Computer Science is applied to the Arts) the pace and breadth would also be suitable for a one semester introductory programming course for all computing undergraduates. We hope that the example programs, chosen to enliven and motivate will also be very relevant to a range of courses and the varied ambitions of people who need to acquire programming skills. The book covers programming from small script-style applications to larger pieces of software. The emphasis remains on problem-solving, even through the introduction of common libraries and object-oriented programming. Test-oriented development is an integral part of programming and learning how to incorporate a unit test early on will take away the frustrations of producing buggy software that doesna t run. It will provide a framework to support your learning of programming.

Whilst both collective and collaborative drawing is being widely explored internationally, both within and beyond educational institutions, there is surprisingly little serious research published on the topic. This realisation led to the first international Drawing Conversations Symposium, accompanied by the Drawn Conversations Exhibition at Coventry University, UK, in December 2015. The two events drew a strong and global response, and brought together a wide range of participants, including academics, artists, researchers, designers, architects and doctoral students. This book considers what happens, and how, when people draw together either in the form of a collaboration, or through a collective process. The contributions here serve to establish the field of collective and collaborative drawing as distinct from the types of drawing undertaken by artists, designers, and architects within a professional context. The volume covers conversations through the act of drawing, collaborative drawing, drawing communities, and alternative drawing collaborations.

The sampling lattice used to digitize continuous image data is a signi?cant determinant of the quality of the resulting digital image, and therefore, of the e?cacy of its processing. The nature of sampling lattices is intimately tied to the tessellations of the underlying continuous image plane. To allow uniform sampling of arbitrary size images, the lattice needs to correspond to a regular - spatially repeatable - tessellation. Although drawings and paintings from many ancient civilisations made ample use of regular triangular, square and hexagonal tessellations, and Euler later proved that these three are indeed the only three regular planar tessellations possible, sampling along only the square lattice has found use in forming digital images. The reasons for these are varied, including extensibility to higher dimensions, but the literature on the rami?cations of this commitment to the square lattice for the dominant case of planar data is relatively limited. There seems to be neither a book nor a survey paper on the subject of alternatives. This book on hexagonal image processing is therefore quite appropriate. Lee Middleton and Jayanthi Sivaswamy well motivate the need for a c- certedstudyofhexagonallatticeandimageprocessingintermsoftheirknown uses in biological systems, as well as computational and other theoretical and practicaladvantagesthataccruefromthisapproach.

The audience for this book is everyone that has an interest in the images they see daily. Regardless of your occupation or station in life, you are affected daily by image processing. Even readers who are not computer literate will find this book informative. The book starts very simply--describing image processing, then progresses to more advanced concepts such as video morphing.

With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information. Image data protection and image-based authentication techniques offer efficient solutions for controlling how private data and images are made available only to select people. Essential to the design of systems used to manage images that contain sensitive data—such as medical records, financial transactions, and electronic voting systems—the methods presented in this book are useful to counter traditional encryption techniques, which do not scale well and are less efficient when applied directly to image files. An exploration of the most prominent topics in digital imaging security, this book discusses: Potential for sharing multiple secrets Visual cryptography schemes—based either on the probabilistic reconstruction of the secret image, or on different logical operations for combining shared images Inclusion of pictures in the distributed shares Contrast enhancement techniques Color-image visual cryptography Cheating prevention Alignment problems for image shares Steganography and authentication In the continually evolving world of secure image sharing, a growing number of people are becoming involved as new applications and business models are being developed all the time. This contributed volume gives academicians, researchers, and professionals the insight of well-known experts on key concepts, issues, trends, and technologies in this emerging field.
