    • Wavelet based real-time smoke detection in video 

      Uǧur Töreyin, B.; Dedeoǧlu, Y.; Enis Çetin, A. (2005)
      A method for smoke detection in video is proposed. It is assumed the camera monitoring the scene is stationary. Since the smoke is semi-transparent, edges of image frames start loosing their sharpness and this leads to a ...

    • What is usual in unusual videos? trajectory snippet histograms for discovering unusualness 

      Iscen, A.; Armagan, A.; Duygulu, P. (IEEE Computer Society, 2014)
      Unusual events are important as being possible indicators of undesired consequences. Moreover, unusualness in everyday life activities may also be amusing to watch as proven by the popularity of such videos shared in social ...
    • What's news, what's not? Associating news videos with words 

      Duygulu, P.; Hauptmann, A. (Springer, 2004)
      Text retrieval from broadcast news video is unsatisfactory, because a transcript word frequently does not directly 'describe' the shot when it was spoken. Extending the retrieved region to a window around the matching ...
    • When silence may mean derision 

      Akman, V. (1994)
    • Whole genome sequencing of Turkish genomes reveals functional private alleles and impact of genetic interactions with Europe, Asia and Africa

      Background: Turkey is a crossroads of major population movements throughout history and has been a hotspot of cultural interactions. Several studies have investigated the complex population history of Turkey through a ...
    • Whole genome sequencing: revolutionary medicine or privacy nightmare? 

      Ayday, E.; Cristofaro, Emiliano De; Hubaux, Jean-Pierre; Tsudik, G. (Institute of Electrical and Electronics Engineers, 2015)
      Whole genome sequencing will soon become affordable for many individuals, but thorny privacy and ethical issues could jeopardize its popularity and thwart the large-scale adoption of genomics in healthcare and slow potential ...
    • Whole-genome shotgun sequence CNV detection using read depth 

      Kahveci, Fatma; Alkan, Can (Humana Press, 2018)
      With the developments in high-throughput sequencing (HTS) technologies, researchers have gained a powerful tool to identify structural variants (SVs) in genomes with substantially less cost than before. SVs can be broadly ...
    • A Wi-Fi cluster based wireless sensor network application and deployment for wildfire detection
