Good quality terrain models are becoming more and more important, as applications such as runoff modelling are being developed that demand better surface orientation information than is available from traditional interpolation techniques. A consequence is that poor-quality elevation grids must be massaged before they provide useable runoff models. Rather than using direct data acquisition, this...

We propose a biologically motivated computational step, called surround inhibition, which improves the performance of contour detectors. The mechanism of surround inhibition is exhibited by the majority of the orientation selective neurons in the primary visual cortex of macaque monkeys and has been demonstrated to influence the visual perception of man as well. We illustrate the principle and ...

In the history of surveying and mapping, a large volumes of topographic maps and digital elevation models have been created at various scales throughout the world. However, positional errors and geometric distortions may exist in the topographic contour maps and their derived DEMs due to inaccurate ground control and poor navigation techniques in the early years. In this paper, we present a new...

Eight boron compounds are investigated in this study. Structural and spectral characterization is done at M062X/6-311G(d) level the water. Active sites of these determined using contour plots frontier molecular orbital, electrostatic potential (MEP) maps MEP contour.. Electrophilic nucleophilic attack regions determined. We aimed to determine whether inhibitor used treatment omicron variant SAR...

Livestock management involves the monitoring of farm animals by tracking certain physiological and phenotypical characteristics over time. In dairy industry, for instance, cattle are typically equipped with RFID ear tags. The corresponding data (e.g. milk properties) can then be automatically assigned to respective cow when they enter milking station. order move towards a more scalable, afforda...

We present a multi layer, hierarchical neural system for automatic classiication of complex contour patterns. The system consists of a Neocognitron-like network structure combined with Self Organising Maps to automatically determine feature classes. We present results showing that multi-layer hierarchical networks are able to tolerate pattern distortion considerably better than standard neural ...

This paper describes a general system which maps from a phonological specification of an utterance’s intonation to a F0 contour. The system can accommodate a variety of feature based phonological description schemes. Speaker dependent characteristics can be modelled and an automatic method of determining these is described.

Groundwater, being a vital resource, needs to be developed with proper understanding about its occurrence in time and space. Unscientific sand mining is a dominant environmental issue in this humid tropical river basin namely Bharathapuzha river basin geographically on central part of Kerala state, southwest part of India. The sandy layers along the river course declines its water holding capac...

The region of North-west Bohemia has been influenced by the open cast mining for more than the last hundred years. During this period has the coal mining activity become very intense leaving huge change on the landscape. We may require the original landscape for many purposes (historical, landscape renewal). One of the ways how to reconstruct the original shape of the landscape is the usage of ...
