Piscitelli, R. (author), Bhasin, S. (author), Regazzoni, F. (author)Faults attacks are a serious threat to secure devices, because they are powerful and they can be performed with extremely cheap equipment. Resistance against fault attacks is often evaluated directly on the manufactured devices, as commercial tools supporting fault evaluation do not usually provide the level of details needed to assert the...conference paper 2015

Thomas, E.D.R. (author), van Deventer, M.O. (author), Stockhammer, T. (author), Begen, A.C. (author), Famaey, J. (author)MPEG DASH provides formats that are suitable to stream media content over HTTP. Typically, the DASH client adaptively requests small chunks of media based on the available bandwidth and other resources. This client-pull technology has proven to be more flexible, firewall-friendly and CDN-scalable than server-push technologies. However, service...article 2015

de Boer, M.H.T. (author), Brandt, P. (author), Sappelli, M. (author), Daniele, L.M. (author), Schutte, K. (author), Kraaij, W. (author)One of the challenges in the field of content-based image retrieval is to bridge the semantic gap that exists between the information extracted from visual data using classifiers, and the interpretation of this data made by the end users. The semantic gap is a cascade of 1) the transformation of image pixels into labelled objects and 2) the...article 2015

de Boer, M.H.T. (author), Daniele, L.M. (author), Brandt, P. (author), Sappelli, M. (author)Abstract—With the growth of open sensor networks, multiple applications in different domains make use of a large amount of sensor data, resulting in an emerging need to search semantically over heterogeneous datasets. In semantic search, an important challenge consists of bridging the semantic gap between the high-level natural language query...conference paper 2015

de Boer, M.H.T. (author), Schutte, K. (author), Kraaij, W. (author)A common approach in content based video information retrieval is to perform automatic shot annotation with semantic labels using pre-trained classifiers. The visual vocabulary of state-of-the-art automatic annotation systems is limited to a few thousand concepts, which creates a semantic gap between the semantic labels and the natural language...article 2015
