This paper presents a novel algorithm of hiding
secret messages by applying mathematical lemmas and
information theory. The proposed algorithm can hide more
information with acceptable embedded rate and achieves
requirements of information hiding algorithm and simply
information extracting. The main idea is applying modern
algebra to solve the information hiding problem in multimedia.
In order to prevent some attacks on stganography, hidden
initial bits of image data pixels are chosen randomly. The
extracted information are achieved without the reference of the
original image and extracted keys. The experiment results
show that our approach is effective and reliable.

ovsf
orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutually orthogonal to each other.
These codes are derived from an OVSF code tree, and each user is given a different, unique code. An OVSF code tree is a complete binary tree that reflects the construction of Hadamard matrices.

AFA
自适应滤波器的特点是自动调节自身的冲激响应,达到最优滤波,此算法适用于平稳和非平稳随机信号,并且不要求知道信号和噪声的统计特性。(Adaptive filter is characterized by automatic adjustment of its own impulse response, the optimal filtering, this algorithm applied to a smooth and non-stationary random signal, and does not demand to know the signal and noise is investigated.)

matlab-import-dxf
用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径,缺少圆弧起始角及终止角,并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)
