Integral Imaging (InIm) is a promising three-dimensional (3D) content creation and delivery technique. The simplicity of the method constitutes a straightforward and compact way for acquiring and displaying 3D data. However issues like integrity and authentication of a transmitted InIm are not discussed in the literature. In this paper we propose a jointly optimized InIm fragile self watermarking...
By embedding some information into different resolutions of videos and combining the video segments together, the paper proposed a H.264 information hiding algorithm in video stream switching application. Detailed embedding course carries out in the movement vector after H.264 compression, and the embedding needn't to be operated while the video being transmitted, making the real-time performance...
In the fragile digital color image watermarking for RGB color image authentication, fragility or sensitivity of the embedded watermark to malicious attacks is an important problem. In this work the current researches propose Bit Plane Index Modulation (BPIM) based fragile watermarking scheme for authenticating RGB color image. To deal with counterfeiting attacks block wise division dependency is established...
H.264/AVC is a novel video coding standard that provides better coding efficiency than previous video coding standards. It adopts many predictive coding algorithms to improve the coding efficiency of intra and inter frames. Due to its characteristics of high compressibility, it can achieve high quality at low bit rate. Therefore, more and more applications adopt H.264/AVC codec. Nowadays, a great...
With the proliferation of digital multimedia content, issues of copyright protection have become more important in video retrieval system because the copying of digital video does not result in the decrease in quality that occurs when analog video is copied. One method of copyright protection is to embed a digital code, ldquowatermarkrdquo, into the video sequence. The watermark can then unambiguously...
This paper presents a novel information hiding algorithm for AVS (audio video coding standard), taking advantage of the specific features of this self developed Chinese audio video compression standard. AVS adopts Exp-Golomb coding and context based adaptive variable length coding to solve the entropy coding problem, almost all the syntax elements are encoded using Exp-Golomb codes. In the compressed...
