图像分割是进行图像理解与分析的基础,是图像工程技术中的一个重要问题, 也是图像处理的经典难题。彩色图像比灰度图像具有
更多的视觉信息, 因而受到了越来越多的重视。文章将彩色图像的分割技术分为三大类,并分别加以系统概括, 分析了各种方法的优缺点。(Image segmentation is the image understanding and analysis of the basis of the image engineering technology is an important issue, but also the classical image processing problems. Color image than the gray image with more visual information, which are more and more attention. Article will color image segmentation techniques into three categories, and to the system were summarized, analyzed the advantages and disadvantages of each method.)

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.
