ABSTRACT Fractal image coding, which is also called attractor image coding, is a emergent method of image compression during the last decad...

分形图像编码方法是近十年来诞生并发展起来的一种新型图像压缩方法，它将图像编码为一组收缩映射，由这组收缩映射的不动点近似待编码对象。

Firstly, chaotic kinetic characteristic of Kent mapping is analyzed, using it to encrypt watermark image; Secondly, an algorithm of only modifying the decimal part of DC components is given, bringing the least error, effectively solving the problem which embedding watermark in DC components is easy to the image's block effect; Watermark is extracted without original image utilizing two-bits algorithm.

深入分析了帐篷映射的混沌动力学特性，并将其应用于水印图像的预处理；在分析了 DCT域嵌入对策的基础上提出了一种只修改 DC 分量小数部分的嵌入算法，引入的误差小，有效的解决了以往人们在 DC 分量嵌入水印容易引起图像块效应的问题；检测过程中利用二值离散算法使得水印提取时无需原始图像。

In view of the above steps a second phenomenon, clone the operating system is to store the default camera driver in C: \ Windows \ Driver \ Camera \ 301P the following folder, when you click on the new CD-ROM drive to install the camera, the system will not prompt already exists there and the camera drivers to uninstall this driver, please find this folder and removed; step II, first to install a new camera driver, and then plug in the camera loaded with hardware, the installation is complete restart the computer after normal use; step three, repeat the above two steps do not directly click on the new CD-ROM installation the latest drivers, plug in the camera after the system detects new hardware and auto-complete loading hardware drivers; step four, entered the Device Manager, can see the image processing equipment has been successfully installed, but when you open the "AMCAP" Preview images can not be preview, black and white, black phenomenon; five steps to the right mouse button on the image processing equipment "Vimicro USB PC Camera (ZC0301PL)" update driver, a dialog box appears choose "from the list or designated as the location of the installation steps to choose the next six to choose "Do not Search" and enter "to install from the floppy disk interface.

针对以上第二种现象步骤一、克隆操作系统是将摄像头驱动默认存放在C：\Windows\Driver\Camera\301P文件夹下面，当你点击新的摄像头驱动光盘安装时，系统不会提示已经存在有摄像头驱动并把此驱动卸载，请把这个文件夹找到并删除掉；步骤二、先安装新的摄像头驱动，再插上摄像头装载硬件，安装完成后重新启动电脑后可以正常使用；步骤三、不需重复以上两个步骤，直接点击新的光盘安装最新的驱动，插上摄像头后系统检测到新硬件，并自动完成硬件驱动装载；步骤四、进入到设备管理器中，，可以看到图像处理设备已经成功安装，但当你打开"AMCAP"预览图像时会出现无法预览、白屏、黑屏现象；步骤五、把鼠标右键放在图像处理设备的"Vimicro USB PC Camera（ZC0301PL）"更新驱动程序，出现对话框后选择"从列表或指定为位置安装步骤六选择下一步后选择"不要搜索"，进入"从软盘安装界面。

The experimental results show that original image corresponding to motion blurred one can be found accurately according to the features extracted by ICA,and the proposed algorithm is reasonably robust in noise,rotation and defectiveness.

实验结果表明，利用ICA算法提取出的特征可以准确地检索出运动模糊图像的原图像，并且对噪声污染、旋转变换和图像缺损具有良好的鲁棒性。

The cheapness of instant photography, the simplicity of image producing technology, the visual subversion of finished images by computer PS technology, and the visual overflow of web communication all help turn us into a blind herd and involve us in a deicide carnival aiming to subvert the conventional sense of awe of images.

在数码时代，人们却通过着即拍即得的廉价性、图像产品生成技术的简单性、电脑PS技术对于图像篡改的视觉颠覆性、网络传播方式的视觉泛滥性使我们成为盲目的群氓，参与到了一场具有颠覆着传统的图像敬畏感的弑神狂欢中。

This is an image interception of the tool, the depositary for the interception of images JPEG or BMP functions,...

这是一个图像截取的工具，实现了截取图像保存为BMP或者JPEG的功能，按照自定义的方式进行图像的截取，较方便！

Firstly, a quantitative relation about finite deformation and geometrical parameters which exhibit variation of laser spectral image was introduced. And then, particular emphasis was put on some important computer processing steps related to the analysis of spectral image, such as digitizing, segmentation, feature extraction and analytical algorithms. Lastly, some examples about an experiment of a ring subject to large diametral compression were given.

文中首先给出了有限应变和平均整旋角与反映频谱图像变化的几何参数之间的定量关系，然后着重介绍了与频谱图像分析有关的数字化、分割、特征提取和分析算法等重要的图像处理过程，最后给出圆环受径向荷载大变形实验的分析实例。

The ship image sequence can be stabilized using this algorithm and the results can be assessed by the fidelity of image sequence and image difference.

将此算法应用於舰船图像序列稳定实验，分别采用图像差值和图像序列的逼真度对稳定的结果进行了评定。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
