“Master terrainer Harwood offer[s] advice on 10 projects, from the mosque on the cover to mud-brick buildings to grass huts... he knows his stuff.” —Historical Miniatures Gaming SocietyThe Middle East and North Africa have been the backdrop for many conflicts through the centuries, making them a popular setting for miniature wargames. Whether you are fielding your Parthians against invading Roman legions, Crusaders against Saladin's Saracens, recreating Lawrence's exploits in Arabia, or trying to halt Rommel at El Alamein, this book will help you set the scene for your games.Expert terrain modeler Tony Harwood takes the reader through a range of projects step by step, from selection of materials to the finished items. Each stage is illustrated with color photographs. The projects have been selected to provide a useful range of features but also to introduce materials and techniques the reader can then apply to further buildings and terrain pieces. Included are a range of traditional mud-brick dwellings/shops, mosque, well, palm trees, rocky outcrop, Bedouin tent, El Alamein railway station, Sudanese huts, colonial river gunboat. They are easily adaptable to different scales. Suited to novice and experienced modelers alike.“Soon your DAK or Desert Rat themed builds will look right at home in their natural setting. No matter your skill level, the information in the book will give you all you need to dive right in and give it a try!” —AMPS “A lavishly illustrated how to book full of full color photographs detail[ing] the construction of 9 buildings and 1 gunboat in a spread of 15mm and 28mm scales... full of useful tricks and tips.” —History of War

Mathematical morphology has developed a powerful methodology for segmenting images, based on connected filters and watersheds. We have chosen the abstract framework of node- or edge-weighted graphs for an extensive mathematical and algorithmic description of these tools. Volume 1 is devoted to watersheds. The topography of a graph appears by observing the evolution of a drop of water moving from node to node on a weighted graph, along flowing paths, until it reaches regional minima. The upstream nodes of a regional minimum constitute its catchment zone. The catchment zones may be constructed independently of each other and locally, in contrast with the traditional approach where the catchment basins have to be constructed all at the same time. Catchment zones may overlap, and thus, a new segmentation paradigm is proposed in which catchment zones cover each other according to a priority order. The resulting partition may then be corrected, by local and parallel treatments, in order to achieve the desired precision.

Mathematical morphology has developed a powerful methodology for segmenting images, based on connected filters and watersheds. We have chosen the abstract framework of node- or edge-weighted graphs for an extensive mathematical and algorithmic description of these tools.Volume 2 proposes two physical models for describing valid flooding on a node- or edge-weighted graph, and establishes how to pass from one to another. Many new flooding algorithms are derived, allowing parallel and local flooding of graphs. Watersheds and flooding are then combined for solving real problems. Their ability to model a real hydrographic basin represented by its digital elevation model constitutes a good validity check of the underlying physical models. The last part of Volume 2 explains why so many different watershed partitions exist for the same graph. Marker-based segmentation is the method of choice for curbing this proliferation. This book proposes new algorithms combining the advantages of the previous methods which treated node- and edge-weighted graphs differently.

It focuses on principles and methods and presents an integrated treatment of airborne and terrestrial laser scanning technology. It brings together the various facets of the subject in a coherent text that will be relevant for advanced students, academics and practitioners.

This title helps modellers who wish to display the results of their efforts to the best advantage in a diorama. This book provides detailed information on how to create many different types of terrain; the paints, glues, tools and materials that will be of help to the modeller; and how these can be obtained both in Europe and the USA. Illustrated with some 200 photographs and written by a master of diorama modelling with a lifetime's experience, this book provides the essential and invaluable guide to the materials and techniques needed to create top quality terrain for anywhere from Ancient Rome to the Western Front.
