Georeferenced road extraction and formulation of hypotheses for new road segments
(2000-01-01)
The acquisition and update of Geographic Information System (GIS) data are typically carried out using aerial or satellite imagery. Since new roads are usually linked to georeferenced pre-existing road network, the extraction ...
Extracting information from PDF documents for use in automatic indexing of e-books
(Pontificia Universidade Catolica Campinas, 2022-01-01)
The number of electronic books that enter libraries in PDF format is greater every day. Complicating and making it almost unfeasible for some processes, traditionally carried out manually by librarians such as the assignment ...

Information extraction with active learning : a case study in legal text
(2015)
Active learning has been successfully applied to a number of NLP tasks. In this paper, we present a study on Information Extraction for natural language licenses that need to be translated to RDF. The final purpose of our ...
Active testing and edge analysis for road centreline extraction
(2002-01-01)
As in the foreseeable future a human will be expected to remain as part of the object extraction system, semi-automated road extraction methods are still important. Following this trend, this paper presents a semi-automated ...
Extraction of building roof planes with stratified random sample consensus
(2018-09-01)
This paper describes a consensus-set estimation for building roof-plane detection using a stratified random sample consensus (sRANSAC) algorithm applied to point clouds acquired by laser scanning systems. The main idea is ...
