An oblivious video watermarking method is presented based on the temporal sensitivity of Human Visual System (HVS). The method exploits the temporal contrast thresholds of HVS to determine the maximum strength of watermark, which still gives imperceptible distortion after watermark insertion. Compared to other approaches in the literature, the method guarantees to avoid flickering problem in the watermarked video and gives better robustness results to video distortions, such as additive Gaussian noise, H.263+ coding at medium bit rates and frame averaging in terms of bit error rate.

Oblivious video watermarking using temporal sensitivity of HVS
Koz, A; Alatan, Abdullah Aydın (2005-09-14)
A novel oblivious video watermarking technique based on temporal sensitivity of Human Visual System (HVS) is proposed. The method exploits the temporal contrast thresholds of HVS to determine the maximum strength of watermark, which still gives imperceptible distortion after watermark insertion. Compared to the other methods in the literature, which do not use any HVS properties explicitly [12] or exploits only spatial properties of HVS [13], the proposed method guarantees to avoid flickering problem in the...
Temporal watermarking of digital video
Koz, A; Alatan, Abdullah Aydın (2003-04-11)
A video watermarking method is presented, based on the temporal sensitivity of Human Visual System (HVS). The method exploits the temporal contrast thresholds of HVS to determine the spatio-temporal locations, where the watermark should be embedded, and the maximum strength of watermark, which still gives imperceptible distortion after watermark insertion. The robustness results indicate that the proposed scheme survives video distortions, such as additive Gaussian noise, ITU H.263+ coding at medium bit rat...
E3D-D2D: EMBEDDING IN 3D, DETECTION IN 2D THROUGH PROJECTIVE INVARIANTS
Yasaroglu, Yagiz; Alatan, Abdullah Aydın (2014-10-30)
A novel watermarking method is presented in which the data embedded into a 3D model is extracted from an arbitrary 2D view by using a perspective projective invariant. The data is embedded into 3D positions of selected interest points on a 3D mesh. Determining the interest point modification vectors for ensuring watermark detection constitutes an important part of the proposed method. Different watermark embedding schemes based on optimization of the watermark function are implemented and evaluated. Another...
Multimodal query-level fusion for efficient multimedia information retrieval
Sattari, Saeid; Yazıcı, Adnan (2018-10-01)
Managing a large volume of multimedia data containing various modalities such as visual, audio, and text reveals the necessity for efficient methods for modeling, processing, storing, and retrieving complex data. In this paper, we propose a fusion-based approach at the query level to improve query retrieval performance of multimedia data. We discuss various flexible query types including the combination of content as well as concept-based queries that provide users with the ability to efficiently perform mu...
Oblivious spatio-temporal watermarking of digital video by exploiting the human visual system
Koz, Alper; Alatan, Abdullah Aydın (2008-03-01)
Imperceptibility requirement in video watermarking is more challenging compared with its image counterpart due to the additional dimension existing in video. The embedding system should not only yield spatially invisible watermarks for each frame of the video, but it should also take the temporal dimension into account in order to avoid any flicker distortion between frames. While some of the methods in the literature approach this problem by only allowing arbitrarily small modifications within frames in di...
