图象

An optical system of measuring system is constituted by a illuminating system and a magnifying system. The illuminating system adopts a far center illuminating mode to make the illumination unified. The magnifying system all adopts object far center optics path to eliminate the error for out of focus. The objective is a plan and apochromat to make image clear. The operator adjusts focus with parameters provided by computer.

论文分析了纤维细度测量系统的光学系统：照明系统采用远心柯勒方式，实现物面的均匀照明；成象系统采用物方远心光路，减少离焦对纤维细度测量的影响；物镜采用平场消色差物镜，消除因为象差引起的图象变形和不清晰，为纤维细度的高精度测量奠定基础；在图象清晰度判别中采用计算机计算参数结合人工调整的方法，既保证结果的客观性，又使系统简化。

According to the Marr's visual theory, a novel face image presentation model, dual attribute graph , is put forward in the thesis. Each node of the graph has two attributes, local principal component coefficient and Gabor coefficient. So the presentation of face image can be converted from gray level to more high level.

根据Marr的视觉表示理论，本文提出了新的人脸图象表示形式---双属性图表示，属性图中每个节点有两个属性特征，局部主成分系数特征以及Gabor系数特征；从而将人脸图象的灰度级表示，转化为更高一级表示。

As the result of using Euclidean norm metric, the performance of traditional FCM clustering algorithm is subject to the structure of sample patterns in feature space.

一是针对SAR图象，提出了基于混合偏移Rayleigh分布假设的最小误差算法；二是针对低质量图象，提出了基于散射图SEM估计的MAP聚类算法。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.

在证明了理想滤波器的不可实现性之后，得知通过选择适当的窗函数可获得很好的滤波函数，经过两个实际滤波器的效果对比，我们选取了较好的"巴拿马帽"形滤波函数，同时也介绍了一个有效的提高重建质量的线性内插函数，概要地叙述了平行射束图象重建的计算机具体实现步骤后，对几个物体的模拟投影数据进行了重建：投影角为180°，每视角下有100个平行投影数据点，在386微机上重建尺寸为64×64，时间约为40秒；在486/33MHz微机上只用了12秒，图象的象点精度是0.31mm。

The basic idea is that using the "point" function of software UTHSCSA Imagetool to acquire the pixel values of the event in the scanned chart image and then process these arc-shaped isochronal data with algorithms proposed by us to render these data.

基本方法是利用图象软件Imagetool中的"Point"功能获取小气候自记图图象上的记录曲线上点的像素值，然后通过我们给出的算法转换成相应的数据资料。

Images include photographic gems by key early circus photographers such as Frederick Whitman Glasier and Edward Kelty, about 180 of the earliest color photographs ever taken of the circus from the 1940s and 1950s, 200 posters by the famous Strobridge lithographers, iconic circus photographs by Mathew Brady, Cornell Capa, Walker Evans, Weegee, Lisette Model, and little-known circus images by Stanley Kubrick and Charles and Ray Eames; also included are rare color and black-and-white lithographs and engravings from the 16th-19th centuries illustrating the worldwide roots of the circus, as well as original sideshow banners by legendary sideshow banner artists Nieman Eisman, Fred G.

图象由钥匙早期的马戏摄影师包括摄影宝石例如 Frederick Whitman Glasier 和爱德华 Kelty ，大约 180 最早期的颜色照片拍摄从 20 世纪 40 年代的马戏和 20 世纪 50 年代，200 张海报由著名 Strobridge 平版家，偶象马戏照片由 Mathew Brady ，康奈尔Capa ，步行者伊万斯、Weegee、Lisette 模型和罕知的马戏图象由斯坦利}39； Kubrick 和查尔斯和光芒 Eames；也包括罕见的颜色和从说明马戏的全世界根的 16 第 19 个世纪的黑白平板印刷和板刻，以及原始的杂耍横幅由传奇杂耍横幅艺术家 Nieman Eisman ，弗雷德 G。

The result showed , the two dimensional image accumulated by photon emission at some hours. The spontaneous luminescence could be measured by means of photon counting and imaging acquisition. The luminescence intensity of root and leaf was different at the same plane image. It showed that PIAS could objectively display the spontaneous ultraweak photon, and this results provided experimental basis for resea...

结果表明，自发光子长时间积累可形成二维图象；光子计数和采集图象均可得到植物体的自发发光；通过实验探测到幼苗的根、叶在同一平面图象有不同的发光表现；光子成像系统可客观地比较生物自发超弱发光，为进一步研究超弱发光机理提供实验基础。

From the concept, it does the exact opposite of a camera: instead of recording an image of the environment by means of an orthographic or perspective projection, projective texture mapping projects an image onto the environment, by using a matrix very similar to the one a camera uses.

从这个概念上，它与摄象机正好相反，不是通过正交或者透视投影来记录环境的图象，而是把图象投射到环境上，通过使用类似于摄象机使用的矩阵。

It offers a more precise way for image analysis than wavelet multi-resolution analysis. Through merging images data of different wavebands from multi-sensor to the same object and different resolution images data by applying image fusion method based on wavelet packet analysis, we get fused pictures.

利用此融合算法将由多传感器获得的同一目标不同波段的遥感图象和不同分辨率的遥感图象进行融合后得到的融合图象，能够很好地将源图象的细节融合在一起。

Normally, in order to improve recognition accuracy and save image rescanning time, software correction is used to correct the slant before next step recognition processes of OCR are executing.

在光学字符识别图象扫描输入的过程中，扫描图象或多或少会出现某种程度的倾斜，这种图象的倾斜不仅会给下一步字符的切割造成困难，也影响最终的字符识别精度。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
