不匹配

SIFT（Scale Invariant Feature Transform） local feature is chosen because of its scale invariance and the property of accurate key-point localization.The Euclidean distance between different SIFT feature vectors is defined as the measure of similarity to get the pre-matched key-point pairs.The affine transform model is used to realize the registration.In order to get the accurate affine transform parameter,the principal of affine transform error is used to get rid of mismatched key-point pairs from the pre-matched pairs.

该方法选取具有良好尺度、旋转不变性以及精确特征点定位能力的SIFT局部特征，使用其特征向量间的欧氏距离作为相似性度量进行特征点匹配，并依据仿射变换误差准则去除奇异匹配特征点对，采用仿射变换的几何模型，实现了遥感图像的快速自动配准。

Because the atomic lattice structure of gallium nitride is better matched to sapphire than it is to silicon making LEDs on silicon without distortions has proved extremely tricky.

由于镓 氮化合物的原子格结构和"蓝宝石"的匹配要比它同硅的匹配效果好所以不进行弯曲来进行 LED灯泡的生产被证明是极其精明的。

Check whether the washing fluid and reaction reagents match, the solution pH value is very important, and the peroxidase substrate solution that matches should not contain sodium azide.

检查冲洗液是否和反应试剂匹配，溶液的pH值很重要，与过氧化物酶底物匹配的溶液中不应含有叠氮钠。

Based on the basic principles of infrared imaging, effect of the difference in the ground resolution of infrared imaging on the invariability of invariable moment features is discussed in this paper.

为了提高实时图像与基准图像的匹配正确率，提出了基于改进不变矩特征的成像匹配方法。

The result shows that the proposed indexing and matching algorithm performs well both in matching speed and in toleration of the non-linear deformation, besides its shift and rotation invariant property.

实验结果表明，本文提出的新的匹配算法除了具有平移、旋转不变性外，在匹配速度和容忍非线性形变方面具有良好的性能。

The proposed indexing and matching algorithm performs well both in matching speed and in toleration of the non-linear deformation, besides its shift and rotation invariant property.

同时表明本文所提出的匹配算法除了具有平移、旋转不变性外，在匹配速度和容忍非线性形变方面具有良好的性能。

With the segmented mass contour, spiculated tissues surrounding the mass are detected, and a quantitative spiculation index is computed to assess the degree of spiculation.

其次，根据同一病患同侧乳腺组织拍摄的CC视图和MLO视图中相应肿块病灶区域在中轴线上的投影点与乳头之间的距离基本保持不变的性质，匹配了多视图中相应的可疑病灶区域，并基于匹配区域对提取了视图不变性特征和相似性度量特征。

The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map.

前者匹配效率高，稳定性好，对图象的非本质的变化不敏感；而后者利用图象中的所有信息，所以区分不同图象的能力强，精度高，特别是它能在十分复杂的图象环境下(此时很难甚至不可能使用特征匹配法)有效地工作。

Because the lookahead expression is not backtracked, the matching engine does not retry group 1 with fewer "a" characters.

由于向前查找表达式是不进行回溯的，所以匹配引擎〔注4〕不会重新尝试让组 1 匹配更少的字符 a〔注5〕。

I draw people through the test, understand the different classes of children aged people in figure painting tests on the following characteristics: 1, small classes can not find child care because of the graphic match, the majority of child care both in the overall figures are still details to chaos The lines to express disorder. 2, Zhongban due to the continuous improvement of cognitive, has been able to find a match in the minds of the graphics, and has been in the minds of the graphic expression, but the details painted on the expression of often rough. 3, taipans child care whether or details on the whole, are more perfect expression, but the large class paintings by children of mothers are the embodiment of their own, can not distinguish between adults and children.

笔者通过画人测验，了解不同年龄班的幼儿在人物画人测验上有以下的特点：1、小班幼儿由于找不到匹配的图形，大部分幼儿无论是在人物整体上还是细节上都是用混乱无序的线条来表达。2、中班由于认知的不断提高，已经能在头脑中找到相匹配的图形，并将头脑中已有的图形表达出来，但是在细节描绘上表达的往往比较粗略。3、大班幼儿无论是在整体上还是细节上，表达的都比较完善，但是大班幼儿所画的妈妈都是自己的化身，不能区分大人和小孩。
