ADAPTATION OF ROADS TO ALS DATA BY MEANS OF NETWORK SNAKES
snakes networks vector data roads ALS intensity topology consistency
2016/2/29
In the Authoritative Topographic Cartographic Information System (ATKIS®), which is the main public topographic data base in
Germany, the heights and the 2D positions of objects such as roads a...
Semiautomatic Extraction of 3D Curves Based on Snakes and Generalized Point Photogrammetry from Aerial Imagery
Photogrammetry Feature Extraction Building Edge Aerial Imagery
2015/12/9
The Snakes or active contour models of feature extraction algorithm integrates both photometric and geometric constraints. It derives the feature of interest by minimizing the total energy of Snakes w...
Topology-Preserving Network Snakes
Computer Vision Active Contour Models Optimization Segmentation Networks Topology Roads
2015/12/4
Active contour models have been part of extensive research since their introduction in the late eighties, because their concept of coupling the image data with shape control is a powerful method to de...

or quickly populating GIS database, it is important to derive accurate and truly road information from imagery. In this paper, we
describe the problem of urban road extraction from digital imagery u...
Snakes and snake-like robots show how sidewinders conquer sandy slopes（图）
robots sandy slopes
2014/12/1
The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a un...
Snakes and ladders: localized solutions of plane Couette flow
Snakes ladders plane Couette flow
2010/4/7
We demonstrate the existence of a large number of exact solutions of plane Couette flow, which share the topology of known periodic solutions but are localized in space. Solutions of different size ar...
