Automatic urban area detection in remote sensing images is an important application in the field of earth observation. Most of the existing methods employ feature classifiers and thereby contain a data training process. Moreover, some methods cannot detect urban areas in complex scenes accurately. This letter proposes an automatic urban area detection method that uses multiple features that have different...
A novel navigation system for the blinds is developed. A multi-functional navigation system is implemented on the Windows Mobile platform by extracting signals from Global Positioning System (GPS) as well as applying custom-built map sources. The Dijkstra's algorithm is optimized to tackle issues encountered in real-life applications. An external GPS receiver is attached, allowing more accurate localization...
In this paper the concepts of the circulation economy and unpolluting building were describes, the basis for the application of circulation economy in green building was analyzed, and the operational mechanism of the circulation economy in the development of the green building was investigated, the policies and measures of the circulation economy in the development of the green building were advanced.
The old buildings are a kind of material witness and carrier of urban culture continuity, which embody the preservation value of cultural heritage. Facing the fact of architectural culture disappearing in the urbanization process, it is a serious problem to solve: how to properly deal with the contradiction between the protection and reuse of old buildings and the urbanization, and how to inherit,...
