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。

This paper proposes a novel algorithm of Feature Match Based on Corner Affine Invariant. It selects corners as extracting feature of the image matching, and these corners are characterized by their orientation and angular width.

该方法是使用角作为图像匹配选取的特征，通过仿射不变处理来消除图像缩放、扭曲、旋转和平移产生的影响，实验表明，该算法具有良好的匹配性能，可以对差异较大的图像对进行特征匹配

People have proposed lots of feature extraction and classification algorithms and achieved great successful in the last few years, but there are also many disadvantages that restrict the applications to some extent. Rotation invariant and antinoise texture classification is a topic to be researched deeply.

近年来，人们提出了各种纹理分类算法，并取得了丰硕的成果，但是，目前大多数分类算法仍存在很多缺陷，在一定程度上制约了这些算法的应用，旋转不变和具有抗噪性的纹理分类更是有待深入研究的重要课题。

Warning: Don't slide your nondominant hand toward a Continental grip; this will cause the racquet face to open up and keep you from getting enough spin on the ball to bring it down into the court.

注意：不要滑动你的辅助手而使握拍姿势变成欧式握法，这样球拍会面向上，使击出的球没有足够的旋转而不能落在对手的场地内。

In this chapter the relationship between PFA and common factor algorithm is discussed throughly in new way.

这对传统的PFA算法是一个改进，因为传统的PFA算法不能同时实现同址方式的计算和免除旋转因子系数的修改。

According to the Source attenuation model, Lambert′s cosine law of diffuse reflection and Phong specular reflection model, 2 equations used to calculate the opacity and intensity of every voxel in the volume data were obtained.

Experiments show that the improve coarseness has higher texture discriminability and better rotation invariance, and that the image retrieval result based on the improved coarseness is superior to that based on the previous coarseness.

实验表明，改进纹理粗糙度具有更强的纹理分辨能力和更好的旋转不变性，基于改进纹理粗糙度的图像检索结果优于基于原有纹理粗糙度的图像检索结果。

Kanade [1] in 1992 proposed a factorization method which can effectively avoid noise interference, while not restricted to a particular motion model, such as pure translation or rotation .

Kanade[1]于1992年提出了一种Factorization的方法，可以有效地避免噪声的干扰，同时不会受限于特定的运动模型，例如单纯的平移或是旋转。

He also composed music, notably a string quartet in early classical style , and invented a much-improved version of the glass harmonica , in which each glass was made to rotate on its own, with the player's fingers held steady, instead of the other way around; this version soon found its way to Europe.

他还包括音乐，尤其是弦乐四重奏早期古典风格，并发明了一种大大改进版本的玻璃口琴，每个玻璃了旋转，同时其播放器的手指保持稳定，而不是其他方式周围；这个版本很快找到了自己的欧洲。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
