    The MPEG-4 video standard is nowadays more and more used for applications such as video editing, Internet or wireless video communications. This growing development has shown that these data must have a copyright protection such as watermarking. However one of the key points of the MPEG-4 video standard is the possibility to access and manipulate objects within a video sequence. And this particula... View full abstract»

    This paper is devoted to subjective and objective tests of image quality. The images were processed using different compressing algorithms (JPEG, KLT, Lura-wavelet) with compression ratio up to 100. After decompression they were tested on the quality changes. At first the subjective image quality test (DSCQS) was used. Then the objective quality test using the metric based on the human visual syst... View full abstract»

    This paper describes a high capacity blind video watermarking system invariant to geometrical attacks such as shift, rotation, scaling and cropping. A spatial domain reference watermark is used to obtain invariance to geometric attacks by employing image registration techniques to determine and invert the attacks. A second, high capacity watermark, which carries the data payload, is embedded in th... View full abstract»

    Cited by:  Patents (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (446 KB) | HTML iconHTML

    We propose a watermarking scheme applied to digital audio signals. The goal of the project is to hide information which can identify both the tracks and the user who requests them. This technique is used for automatic identification of audio signals in broadcast programs. There are two main features that have to be satisfied: inaudibility and robustness to common editing operations. The algorithm ... View full abstract»

  • On "slant-like" fast orthogonal transforms of arbitrary order

    Publication Year: 2002, Page(s):309 - 314
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (547 KB) | HTML iconHTML

    A concept for the construction of fast orthogonal transforms with matrices containing one or more predefined rows is proposed. In particular, two new families of "slant-like" transforms with matrices of arbitrary orders, including a constant row and a slant row of arbitrary slanting angle, are introduced. Transforms from these families may be computed with fast regular algorithms suitable for para... View full abstract»

    Although the electronic program guide (EPG) is not any more a "novelty" there are still different concepts about the applications and technical implementation of EPG. Such variations raises not only the question of compatibility between different vendors of EPG systems, but cause confusion to consumers: which system is most suitable to viewers and what are the criteria for suitability of an iTV-EP...

  • Use of area-closing to improve granulometry performance

    Publication Year: 2002, Page(s):303 - 308
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (614 KB) | HTML iconHTML

    We present a new procedure for computing the granulometry function. Computation of granulometry is normally done by morphological opening/closing performed on an image with structuring elements of increasing size. This can pose problems, if pixels within the image components are not nearly uniform gray level (or have large variations) or if there are patches within the objects of interest. The pro...

    This paper proposes an effective edge detection scheme based on the scale correlation in the wavelet transform that is equivalent to Canny edge detection. A correlation function is defined as the product of two adjacent wavelet subbands to magnify edges while filtering noise. Unlike many multi-scale techniques that form the edge maps on different scales and then synthesize them into a spatial edge... View full abstract»

    More and more broadcasters are turning to DV systems. Until now, there was no easy way to transfer the DV signal to other digital systems. With JVCs SA-DV 60E we have an efficient and easy way to transfer the DV signals to DV9 machines. Sony introduced an option board for the DSR-2000 that converts DVCAM A/V data streams into 50 Mbps conforming to the syntax specification of the 4:2:2P@ML standard... View full abstract»
