    • Contour based smoke detection in video using wavelets 

      Töreyin, B. Uğur; Dedeoğlu, Yiğithan; Çetin, A. Enis (IEEE, 2006-09)
      This paper proposes a novel method to detect smoke in video. It is assumed the camera monitoring the scene is stationary. The smoke is semi-transparent at the early stages of a fire. Therefore edges present in image frames ...

    • Large-area semi-transparent light-sensitive nanocrystal skins 

      Akhavan, Shahab; Güzeltürk, Burak; Sharma, Vijay Kumar; Demir, Hilmi Volkan (IEEE, 2012)
      Large area and semi-transparent highly light sensitive nanocrystal skin is demonstrated via spray-coating nanocrystals on top of polyelectrolyte-polymers based on photogenerated potential buildup where no external bias is ...

    • Wavelet based real-time smoke detection in video 

      Töreyin, B. Uğur; Dedeoǧlu, Yiğithan; Çetin, A. Enis (IEEE, 2005-09)
      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 ...
