A novel robust video hashing scheme is proposed in this paper. Unlike most existing robust video hashing algorithms, the proposed video hash is generated based on the motion vectors instead of the image textures in the video stream. Therefore, neither full decoding of the video stream nor complex computation of pixel values is required. Based on analysis of motion vector properties regarding their suitability for robust hashing, an improved feature extraction mechanism is proposed and several optimization mechanisms are introduced in order to achieve better robustness and discriminability. The proposed hashing scheme is evaluated by a large and modern video data set and the experimental results demonstrate the excellent performance of the proposed hashing algorithm, which is comparable or even better than the complicated texture-based approaches.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
