According to the characteristic of uncooled infrared image,it needs particular image processing algorithm to deal with. In the collection of the image data, it needs reliable, convenient communication interface to realize the collection of the uncooled infrared image data.

根据非制冷红外图像的特点，需要特定的图像算法对其进行处理；在图像数据的采集上，需要有可靠、方便的通信接口来实现红外数据的采集。

The crucial procedure of contour detection for microscopic image of sprayed droplets and measurement of granularity is to segment droplets from background by producing binary images. The singular threshold is uneffective because the image is very different in illumination. In this paper, a fast maximum entropy image thresholding algorithm based on local gray feature is presented to exact sprayed droplets from background and preserve contours of droplets.

雾滴图像的颗粒提取与测量关键是分割出雾滴与背景，生成二值图像，由于雾滴图像光照不均匀，用单一阈值无法兼顾亮区与暗区，本文提出了一种基于局部灰度特性快速最大熵动态阈值选择算法分割出雾滴微粒并提取雾滴轮廓。

The technique of SSD and MPR with Dual-slice spiral CT scanning may obtain the images which can satisfy clinical necessity. This 3-D images in combination with section may supply vast information about impacted teeth in maxilla clinically. It can be used as one exact examining instrument for treatment. maxilla unerupted teeth; spiral CT; 3-dimensional reconstruction

双排螺旋CT表面遮盖法和多平面重建技术能获得满足临床需要的三维图像和多平面重建图像，联合断面图像可为临床提供上颌埋伏牙的大量信息，可作为埋伏牙治疗进一步的精确检查手段。

According to Guangzhou of Xinhua News Agency on April 2 report system of information of image of communal and safe video already was become those who defend public order and safety is important " weapon ", but also exist to cause the problem such as controversy normative and unidentifiedly, easily in its manage and be used.

据新华社广州4月2日电公共安全视频图像信息系统已成为维护公共秩序和安全的重要&武器&，但在其管理和使用中也存在规范不明、易引发争议等问题。4月1日起实施的《广东省公共安全视频图像信息系统管理办法》对公共安全视频图像信息系统的建设范围、建设主体、管理使用以及违反规定的法律责任等做出了明确规定。

Basic operators of color image morphology are established.The result of the experiment demonstrates that the color vector order has good property.The algorithm of color image morphology based on this order can better keep the peripheral information and hue of the image and has the strong point of unnecessity of exchanging between different color spaces.

实验结果表明提出的颜色向量序性能良好，建立在该向量序上的彩色图像形态学算法能够较好的保持图像的边缘信息和色调，并且亮度均匀，与原图像相比对比度均匀增强，重构开算法的实验结果比原文献中方法有了较大的改进；具有不需要在不同的颜色空间之间转换的优点。

In this paper, the noise sources of the EBCCD imaging system have been analyzed and a SNR model has been established. It shows that the SNR of output image is related not only to the input illuminance on the cathode but also to the spatial frequency of the input image. This has been proved by a series of experiment. Unperfectness of the detecting equation has been pointed out in this paper.

分析了电子轰击电荷耦合器件微光成像系统的噪声源，建立了系统的信噪比模型，指出了在微光成像系统本身的增益和量子效率等性能确定的条件下，成像系统输出图像信噪比不仅仅与输入面照度有关，还与输入图像的空间频率有关，并通过实验得到了证明，指出了经典的图像探测方程的不完善之处。

In order to remove the disturbing noise embedded in the image,protect the edge and useful detail information,and improve the visual contrast effect,a new method for image enhancement based on rough sets and wavelet unsharp masking is presented.

为了有效去除图像中的干扰噪音，改善模糊不清晰的有用边缘细节信息，提高图像的层次感和清晰度，提出将粗糙集和小波反锐化掩模相结合的方法来实现图像增强。

Based on fractal coding the index file have two characters: First, similar images have similar iterative function so as to produce similar index file, and the similar index file can retrieval the similar image; Second, unsimilar images have unsimilar iterative function, vice versa.

这个分形编码方法建立的索引文件具有三个性质：(1)相似图像有相似分形函数能产生相似索引文件，相似索引文件能检索到相似图像；(2)不相似图像有不相似分形函数，反之亦然。

It is very important to manage the enormous size of image databases and retrieve images we need. The drawbacks of traditional text-based image retrieval are that it is time consuming and labor consuming when labeling the keywords on the image, which often untruly represent the content of image.

传统的基于文本的图像检索的缺点通常是为图像加上关键字比较费时费力，常常不能准确地反映图像的内容，且带有很强的主观性，不同的人会有不同的理解，这已不能满足用户的迫切需求。

Such system is based on a general image capture hardware system platform using active-pixel CMOS image sensor and TMS320DM642 multimedia DSP, while we consider synthetically about image sensor's performance, calculation ability of system, bandwidth of data link and memory's capacity and I/O speed, etc, and the easy achievement of multi vison sensor system array as well.

该设计基于有源像素CMOS图像传感器和TMS320DM642多媒体DSP的通用图像采集硬件平台，综合考虑了图像传感器的性能、系统运算能力以及数据链路的带宽、存储器的容量和读写速度等因素，同时考虑到可以方便地应用于多视觉传感系统。

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。
