Complex Spatial Filtering with Binary Masks

Applied Optics, 1966
Usually a hologram is produced by means of an interference experiment. Here, however, we let a computer- guided plotter draw the hologram. The plot, which has to be minified and recorded on film, contains no grey, only binary transmittance values. Our binary holograms yield reconstructed images of a quality equal to that of images obtained from usual ...

What is Spatial Complexity?

2020
Spatial complexity is defined here as the difficulty to simplify the structure or form of a 2-and-higher-dimensional surface or object. The study of spatial complexity refers to the geographical space, to mathematically abstract spaces, to physical objects, or to any surface or object, in a n-dimensional space with n equal to two or higher.

Spatial bounding of complex CSG objects

IEE Proceedings - Computers and Digital Techniques, 1995
Several computer graphics algorithms (such as ray-tracing) heavily relate their performances to the efficiency of the tests of intersection between the rays of a light source and the objects of a synthetic scene. Some solid modelling and robotics algorithms need also to test quickly the possible interferences of the different parts of a system such as ...

Complexity and Spatial Networks

2013
The modern spatial economy has a global “networked” character that is generating important socio-economic and political changes. In this respect, new forms of connectivity play a significant role through their dynamic and complex interplay with the economic and political driving forces behind globalization.

Representing Spatial Complex Systems

2000
In the course of the 1970s modern society declined and post-modern society took shape. The transition to the new social organisation was marked by profound changes in the world picture and role of science. Discussions about the environmental question and the global change concept had two consequences: the environment was internalised into political ...

Enigmas of Spatial Complexity

2020
From Thurston’s geometrization theorem to the Banach-Tarski paradox, spatial complexity can be enigmatic, due to singularities, immersions, infinities (e.g. Alexander’s wild knots, Antoine’s necklace, Ford circles, Hilbert curves). Measuring spatial complexity in already “complex” spatial settings constitutes a major challenge for future research, as ...

Complex spatial patterns on planar continua

Physical Review Letters, 1993
The Landau-Ginzburg equations used to describe periodic spatial patterns in two dimensions are extended to a set or spatiotemporal equations. The extension is determined by the requirement that the equations or motion commute with translations, reflections, and rotations in the plane.

Spatial and Temporal Complexity

1974
In the first section we examined some of the mainly holistic studies of lake benthos that have been undertaken. Opponents of this approach would suggest that no two lakes are, in reality, alike and that the complexity of nature prevents the holistic view from achieving its goal of developing general statements about the nature of lakes. In this section
