    • 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 ...
    • Joint estimation and optimum encoding of depth field for 3-D object-based video coding 

      Alatan, A. Aydın; Onural, Levent (IEEE, 1996-09)
      3-D motion models can be used to remove temporal redundancy between image frames. For efficient encoding using 3-D motion information, apart from the 3-D motion parameters, a dense depth field must also be encoded to achieve ...
    • Motion vector based features for content based video copy detection 

      Taşdemir, K.; Çetin, A. Enis (IEEE, 2010)
      In this article, we propose a motion vector based feature set for Content Based Copy Detection (CBCD) of video clips. Motion vectors of image frames are one of the signatures of a given video. However, they are not descriptive ...
    • Moving region detection in wavelet compressed video 

      Töreyin, B. Uğur; Çetin, A. Enis; Aksay, Anıl; Akhan, M. B. (IEEE, 2004)
      In many vision based surveillance systems the video is stored in wavelet compressed form. In this study, an algorithm for moving object and region detection in video that is compressed using a wavelet transform (WT) is ...
    • Real-time smoke and flame detection in video 

      Töreyin, B. Uğur; Dedeoğlu, Yiğithan; Çetin, A. Enis (IEEE, 2005)
      A novel method to detect smoke and/or flame by processing the video data generated by an ordinary camera monitoring a scene is proposed. It is assumed the camera is stationary. Since the smoke is semi-transparent, edges ...
    • Volatile organic compound plume detection using wavelet analysis of video 

      Töreyin, B. Uğur; Çetin, A. Enis (IEEE, 2008-10)
      A video based method to detect volatile organic compounds (VOC) leaking out of process equipments used in petrochemical refineries is developed. Leaking VOC plume from a damaged component causes edges present in image ...
    • 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 ...
    • Wildfire detection using LMS based active learning 

      Töreyin, B. Uğur; Çetin, A. Enis (IEEE, 2009-04)
      A computer vision based algorithm for wildfire detection is developed. The main detection algorithm is composed of four sub-algorithms detecting (i) slow moving objects, (ii) gray regions, (iii) rising regions, and (iv) ...
