Depth-Image-Based Rendering (DIBR) is widely used to generate virtual view of a scene from a known view with associated depth map in 3D video applications. However, disocclusion arises in image warping of DIBR. Many hole-filling methods have been proposed such as constant color, horizontal interpolation, horizontal extrapolation, and variational inpainting,(More)
— A memory efficient hardware string searching engine for anti-virus applications is presented. The proposed QSV method is based on quick sampling of the input stream against fixed-length pattern prefixes, and on-demand verification of variable-length pattern suffixes. Patterns handled by the QSV method are required to have at least 16 bytes, and possess(More)
Currently, most of the watermarking algorithms for H.264/AVC video coding standard are encoder-based due to their high perceptual quality. However, for the compressed video, they increase the computational burden to decode the video, embed the watermark, and then re-encode it. Obviously it is a bottleneck for real-time applications. Conventional(More)
Robustness and imperceptibility are two fundamental criteria for digital watermarking algorithm. In this paper, we present a new RST-invariant (rotation, scaling, and translation) digital image watermarking scheme to embed and detect watermark in DFT domain, which is based on image texture features and the corresponding wedge curves. Experimental(More)
