Compared with the traditional aerospace remote sensing platforms, The UAV was a new remote sensing platform, with the advantages of flexible, easy operation, high resolution and low-cost, which has been successfully applied to various field of the national economy. The manual extraction of buildings is an extremely labor-intensive, time-consuming work. So the automatic extraction of buildings elevation...
From the standpoint of system engineering, multi-level fuzzy method was used to evaluate the safety of floating bridge. Considering the battlefield tactics factor and technical factor, the index system was built and 8 modules for comprehensive factor influence assessment and 24 modules for specific factor influence assessment were included. Expert evaluation method was used to determine the weight...
This paper proposes a novel object-oriented building extraction method based on fuzzy support vector machines (SVM). The choice to adopt an SVM classification technique is motivated by the high number of parameters derived from the feature-extraction phase, which requires a classifier suitable to the analysis of hyper-dimensional features spaces. This method can be divided into two different phases:...
Rapid development of urban area makes data update more often than ever. Building is an important element of geographical information. So, it is important to detect building changes in urban areas timely. This paper proposes a novel technique for building change detection based upon similarity calibration. In this paper, we define the types of building changes clearly, and introduce how to analyze...
