Joint Learning of Contour and Structure for Boundary-Preserved Building Extraction

Remote Sensing, 2021
Most of the existing approaches to the extraction of buildings from high-resolution orthoimages consider the problem as semantic segmentation, which extracts a pixel-wise mask for buildings and trains end-to-end with manually labeled building maps ...

Building extraction from digital elevation models

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003
We aim to extract buildings from Digital Elevation Models. To achieve this goal, we define a point process whose points represent buildings. We then define a density for this point process which is split into two parts. When written as an energy this density consists of two fields : the first one is an "internal field" that allows us to model the prior

Automatic Building Extraction from Terrestrial Laser Scanning Data

Advances in Electrical and Computer Engineering, 2013
The extraction of building from the huge amount of point clouds with different local densities, especially in the presence of random noisy points, is still a formidable challenge.

A Metric for Polygon Comparison and Building Extraction Evaluation [PDF]

IEEE Geoscience and Remote Sensing Letters, 2015
The standardization of evaluation techniques for building extraction is an unresolved issue in the fields of remote sensing, photogrammetry, and computer vision. In this letter, we propose a metric with a working title “PoLiS metric” to compare two polygons.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Building a generic debugger for information extraction pipelines [PDF]

Proceedings of the 20th ACM international conference on Information and knowledge management, 2011
Complex information extraction (IE) pipelines are becoming an integral component of most text processing frameworks. We introduce a first system to help IE users analyze extraction pipeline semantics and operator transformations interactively while debugging.
