Description: A Novel Audio Watermarking Algorithm for
Copyright Protection of Digital Audio
Abstract
Digital watermark technology is now drawing attention
as a new method of protecting digital content from unauthorized
copying. This paper presents a novel audio watermarking
algorithm to protect against unauthorized copying
of digital audio. The proposed watermarking scheme includes
a psychoacoustic model of MPEG audio coding to
ensure that the watermarking does not affect the quality of
the original sound. After embedding the watermark, our
scheme extracts copyright information without access to the
original signal by using a whitening procedure for linear
prediction filtering before correlation. Experimental results
show that our watermarking scheme is robust against
common signal processing attacks and it introduces no audible
distortion after watermark insertion.

Description: 本文提出并得出快速可变块大小运动估计算法，在此基础上分析比较H264、MPEG4、AVC视频编码算法。文中提供的算法减少运算，以较少的运算量获得较高的图像质量。-This paper proposes and investigates fast variable block-size
motion estimation algorithms based on merge and split
procedures for H.264/MPEG-4 AVC video encoding. The
algorithms take advantage of the correlation of the Motion
Vectors (MVs) of the different block-size modes, to achieve
good computation reduction. Experimental results show that the
number of search points can be reduced to about 4 of that
using full-search motion estimation, with negligible quality
degradation.

Description: Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos.

Description: In this paper, we propose a practical method for hardware-
accelerated rendering of the depth image-based representation (DIBR) object,
which is defined in MPEG-4 Animation Framework eXtension (AFX). The
proposed method overcomes the drawbacks of the conventional rendering, i.e. it
is slow since it is hardly assisted by graphics hardware and surface lighting is
static. Utilizing the new features of modern graphic processing unit (GPU) and
programmable shader support, we develop an efficient hardware-accelerated
rendering algorithm of depth image-based 3D object. Surface rendering in re-
sponse of varying illumination is performed inside the vertex shader while
adaptive point splatting is performed inside the fragment shader. Experimental
results show that the rendering speed increases considerably compared with the
software-based rendering and the conventional OpenGL-based rendering
method.
