Abstract In this study, samples of building material additives were analyzed for naturally occurring radioisotope activity such as uranium, radium, and radon. The radon exhalation the annual effective doses, also calculated. activities samples, determined using HPGe gamma spectrometry ionization detector. results used to calculate dose values by RESRAD BUILD code. concentration ranges between 9...

Speech recognition, image processing, and language understanding technologies have successfully been applied to broadcast news corpora to automate the extraction of metadata and make use of it in building effective video news retrieval interfaces. This paper discusses how these multimedia technologies can be adapted to enrich perspectives in exploring cultural heritage documentaries. Through au...

Object recognition and image classification has become an area of intense focus in machine learning and pattern recognition. Building recognition and classification rise into attention in the area of urban reconstruction where a number of images of buildings are used. We first compare different classification approaches to discriminate the class building from the class non-building. The images ...

Building recognition in urban environments aims to identify different buildings in a largescale image dataset. This identification facilitates the annotation of any visual object to a building’s façade and is an essential step in a variety of applications, such as automatic target detection in surveillance, real-time robot localization and visual navigation, architectural design, and 3D city re...
