We propose a new feature extraction method based on two dynamical systems induced by intensity landscape: the negative gradient system and the Hamiltonian system. We build features based on the Hamiltonian streamlines. These features contain nice global topological information about the intensity landscape, and can be used for object detection. We show that for training images of same size, our...

Although it has physical effects, temporary landscape as a new issue provides various potentialas a place events that can’t be ignored because of wide range effects on promoting and upgrading the quality ofspace. The purpose of this study is to analyze the status and mechanism of temporary landscape. As a basic andpractical research, it is done by using the correlation method and descriptive-an...

This work describes a method of analysing fitness landscapes and uses the method to analyse the difficulty of learning goal-scoring behaviour for robot soccer – a problem that is considered to be very difficult for evolutionary algorithms. Learning goal-scoring behaviour can be made easier or harder by varying the amount of expert knowledge provided to the evolutionary process. Expert knowledge...

In the Southwest Mountain areas, successive hydroelectric plant exploitation by humans on Baoxing River can exert a significant impact on regional landscape composition and structure. Taking East Baoxing River Catchment as the study area, the authors developed a method combining Moving Window based Calculation and Spatial Correlation Analysis to analyze the relationship between fragmentation an...

Terrain synthesis is an important field of Computer Graphics that deals with the generation of 3D landscape models for use in virtual environments. The field has evolved to a stage where large and even infinite landscapes can be generated in realtime. However, user control of the generation process is still minimal, as well as the creation of virtual landscapes that mimic real terrain. This the...

3D visualization techniques enable an intuitive mediation of complex, space related facts. Civic participation in community landscape planning or visual simulations of landscapes could benefit from emerging computer graphics technologies. However, interactive visualization tools matching the special needs of landscape planning only exist in their beginnings. In 2000, the Centre for Agricultural...

Landscape connectivity combines a description of the physical structure of the landscape with special species’ response to that structure, which forms the theoretical background of applying landscape connectivity principles in the practices of landscape planning and design. In this study, a residential development project in the southern United States was used to explore the meaning of landscap...

Landscape feature can be classified by creating categories based on aggregation of spatially explicit information. However, many landscape features appear continuous rather than discrete. The aggregation process likely involves loss of information and introduces a variety of uncertainties whose degree and extent may differ spatially. Since landscape classifications have found wide application i...

Connectivity is classically considered an emergent property of landscapes encapsulating individuals' flows across space. However, its operational use requires a precise understanding of why and how organisms disperse. Such movements, and hence landscape connectivity, will obviously vary according to both organism properties and landscape features. We review whether landscape connectivity estima...

Landscape values are addressed by planning tools in several diversified ways. Many European countries have joined the Convention which just turned 20 last year. This work aims at investigating its implementations and relationships with general local tools, focusing on two main objectives: first one concerns analysis of principles regulating regional strategies, deriving from dictates State norm...
