چکیده

This paper presents an algorithm to form a topographic map resembling to the self-organizing map. The idea stems on defining an energy function which reveals the local correlation between neighboring neurons. The larger the value of the energy function, the higher the correlation of the neighborhood neurons. On this account, the proposed algorithm is defined as the gradient ascent of this energy function. Simulations on two-dimensional maps are illustrated.

A New Three-Dimensional Terrain Model Generation and Real Time Rendering Algorithm

Abstract In order to make full use of the topographic map with DWG format and construct 3D terrain model, a new 3D terrain model generation algorithm based on conversion technology is put forward. Firstly, by processing the topographic map with DWG format, we can get the standardized data which can be stored in spatial database. Secondly, the elevation points and the elevation data note text ar...

Automating Image Map Generation Using Satellite Images and Aerial Photos

Image maps generated using satellite images and aerial photos are extremely useful. The map can provide detailed topographic, land-use and land-cover information on earth. With the growing number of satellite and aerial photo data, a technique which can generate/update maps automatically from satellite images and aerial photos is necessary. This paper presents a technique developed at PCI Geoma...

Hierarchical path planning for multi-size agents in heterogenous environments

In this paper we present new techniques for the automated construction of state space representations of complex multiterrain grid maps with minimal information loss. Our approach involves the use of graph annotations to record the amount of maximal traversable space at each location on a map. We couple this with a cluster-based hierarchical abstraction technique to build highly compact yet com...

A self-organizing map of sigma-pi units

By frame of reference transformations, an input variable in one coordinate system is transformed into an output variable in a different coordinate system depending on another input variable. If the variables are represented as neural population codes, then a sigma–pi network is a natural way of coding this transformation. By multiplying two inputs it detects coactivations of input units, and by...
