Firstly, to ensure the security of wartermark,the wartermark image is Arnold scrambled before embedding and expanded to the twifold size of the original image.The corresponding subband data of the watermark and the red,green,blue weight for original image are combined according to the characteristic of the multiresolution decomposition of the wavelet transform.

首先，为保证水印的安全性，在嵌入之前先对水印图像作Arnold置乱处理，再将水印图像位扩展为原始图像的两倍大小；然后根据小波变换的多分辨率分解特性，将位扩展水印和原始彩色图像红色、绿色、蓝色分量对应方向上的子带系数进行组合。

基于内容的图像检索，基于CXIMAGE类的图像检索软件系统，能够实现文件夹下的相似图像检索，并且选择显示的图像。

Image restoration focuses on removing or reducing the degradation which arises during the image acquisition and transportation, making the image restored get close to the ideal undegraded image, the purpose of which is to reconstruct the original image.

图像恢复的目的是消除或者减轻图像获取传输过程中所发生的品质退化现象，逼近没有退化的理想图像，即重建出原始图像。

In this thesis , firstly, TM remote sensing images were geometry rectified , image intensification, mosaic and cropping by using remote sensing image software ENVI, selected computer-aided supervised classification means to cany distribution using TM remote sensing images of qitai County ,and incorporated soil category material to achieve underlaying surface parameter and vegetation cover degree information in the region of interest .

本文运用遥感图像处理软件ENVI对所选的TM遥感图像进行了几何纠正、图像增强、镶嵌和裁剪，选择计算机辅助监督分类方法，对奇台县TM遥感图像进行了解译分类，并结合研究区土壤类型资料得到了研究区下垫面参数和植被盖度信息。

The characteristics of image moments can be applied in manyfields. We apply Tebechbief moment characteristic to match replace of using graycharacteristic as primitives. An area moment has the property of unsensitive to transition,rotation and sealed change of area, the property of area moment is applied in the areamatching approach in our thesis, combined with a new constraint, and a novel area-basedmatching approach is proposed.

文中对Tchebichef正交矩能对图像进行精确重建的原理，利用点矩特征作为匹配基元对图像进行匹配，得到了较好的效果，并讨论了利用图像重建误差图像进行匹配的可能性和有效性；最后通过矩对区域的平移、旋转和尺度变化的不敏感特性，讨论了基于不变矩的区域匹配方法，通过引入相对位置约束提出了一种新的匹配策略。

A new system design based on the conception of SOC is also given. Processing and tracking algorithms. Put forward some IR image algorithms by analyzing the characteristics of IR image such as: low contrast、ununiformity、wide gray dynamic range.

在红外图像处理算法方面，分析了焦平面红外图像具有的低信噪比、宽图像动态范围及图像非均匀性等特性，结合实际硬件条件，提出了直方图归一化、去冗余灰度均衡、受限空域锐化、多帧平均等处理算法，在实际应用中取得良好效果。

In this paper, Winer filter and multi-scale recovery Retinex color image enhancement algorithms are used to improve the picture quality.

因此本文采用Winer滤波来对病害图像进行去除噪声，同时采用多尺度Retinex彩色复原图像增强算法对图像进行增强处理，改善图像质量。

Images tend to just sit there, looking pretty. The alt and title properties say a little something about what the image looks like, but other than that, unless you add some text around it, it just sits there.

图像倾向与保持在原处，看起来很漂亮。alt和title属性显示了一些图像看起来是怎样的的信息，但是除了这个以外，除非你给图像周围添加了一些文字，否则图像仅仅地保持在原位。

One is to understand the Spectral Characteristic Curve; the other is to satisfy the conditions of similar analogy, which means that the spectral characteristics are similar between the studied area and the area for collecting standard spectral curve as well as the area for analogizing.

这一领域已有的研究工作主要集中在如下几个方面：①图像处理，包括以增强和提取成矿信息为目的的图像增强、图像变换和图像分类等；②地质解译；③遥感地面模式的研究；④数据融合；⑤遥感生物地球化学研究。

According to the deficiency of Image Fusion applications in entertainment equipments, such as no special research that combines Virtual Reality, Self-control Photographing, Computer Vision and Image Fusion technologies together, we propose an Image Fusion algorithm base on Character of Apperceiving Contrast, which take system elements into account, e.g. integrity image quality balance and costs.

鉴于目前对图像融合技术在娱乐领域的应用缺乏研究，尤其缺乏将虚拟现实技术、自助照相技术、机器视觉技术和图像融合技术综合运用的分析研究，因此我们从分析人类视觉特征入手，运用系统的观念综合平衡图像质量、系统成本等技术指标，在对虚拟实时自助照相系统具体技术指标深入分析的基础上，提出了基于对比度感知特征（Character of Apperceiving Contrast）的图像融合算法。

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。
