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)
— Most of the TV manufacturers have released 3DTVs in the summer of 2010 using shutter-glasses technology. 3D video applications are becoming popular in our daily life, especially at home entertainment. Although more and more 3D movies are being made, 3D video contents are still not rich enough to satisfy the future 3D video market. There is a rising demand(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)
