Assessing validation methods for building identification and extraction
2015 Joint Urban Remote Sensing Event (JURSE), 2015As data sources and algorithm choices become increasingly more available for automatically extracting and reconstructing 3D buildings, methods are needed to assess the accuracy of the classification process. Our research goal is to compare validation data sources and methods to assess objectivity, sensitivity, and reliability of current validation ...

Contextual keyword extraction by building sentences with crowdsourcing
Multimedia Tools and Applications, 2013Automatic keyword extraction from documents has long been used and proven its usefulness in various areas. Crowdsourced tagging for multimedia resources has emerged and looks promising to a certain extent. Automatic approaches for unstructured data, automatic keyword extraction and crowdsourced tagging are efficient but they all suffer from the lack of

Extracting buildings from aerial topographic maps
Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems. IROS '96, 2002The recovery of 2D information from intensity images, and that of 3D information from range images are the major issues in 3D objects recognition from sensory data. The analysis and interpretation of remote sensing aerial images have important applications.

Building Extraction Method in Remote Sensing Image
2020Identifying buildings in disaster areas quickly and conveniently plays an important role in post-disaster reconstruction and disaster assessment. Aiming at the technical requirements of earthquake relief projects, this paper proposed a building extraction method in remote sensing images by combining traditional digital image processing methods and ...

Building query optimizers for information extraction
ACM SIGMOD Record, 2009Text documents often embed data that is structured in nature. This structured data is increasingly exposed using information extraction systems , which generate structured relations from documents, introducing an opportunity to process expressive, structured queries over text databases.

Building extraction from stereoscopic aerial images
Applied Optics, 2004Three-dimensional models of urban objects are widely used in geographic information systems, telecommunications, or defense applications. The classic technique for obtaining such models is stereoscopy. Images are densely matched, and images of above-ground structures are delineated.

Method for Building Dictionaries to Extract Reputation Information
2008This paper proposes the method of building dictionaries for extracting reputation information. We propose a method of building a highly credible dictionary from the staggering volume of information that customers post on Web pages. The principle of our proposed method is based on assigning a certainty factor which represents the probability that ...

Effectiveness of polarization on the extraction of buildings with different orientations
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015Using the polarization as a scale, we compensated for the azimuth scale effect on the building identification in urban areas. With the increase of polarization dimension (from a single polarization, dual-polarization, to polarimetric data with the rotation of azimuth angle) or change of polarization scale, the azimuth scale effect was gradually ...

Microtiles: Extracting Building Blocks from Correspondences
Computer Graphics Forum, 2012AbstractIn this paper, we develop a theoretical framework for characterizing shapes by building blocks. We address two questions: First, how do shape correspondences induce building blocks? For this, we introduce a new representation for structuring partial symmetries (partial self‐correspondences), which we call “microtiles”.

The texture extraction and mapping of buildings with occlusion detection
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015Texture extraction and mapping is a key step for 3D reconstruction. The major methods are depending on experiences, scene photograph, close-range photogrammetry and oblique photogrammetry. They all require collecting additional images, which it is costly, time consuming and laborious.
