不变

The chief route advocated by this sutra is the extirpation of the negative mental states and immoral modes of behavior (including selfish desire, hatred, ignorance, avarice, and wrong livelihood - such as being a soldier or killer of animals), the cultivation of the paramitas (moral perfections, such as generosity, and meditation), the leading of a pure and harmless life, faithful study, practice and veneration of the Mahaparinirvana Sutra, and the constant meditative cultivation of the idea of the Buddha's eternity, unchangeability and indestructibility.

这个佛经建议的主要路线是消灭负面的心理状态和不道德的行为模式（包括自私的欲望，仇恨，无知，贪婪，和错误的方式-比如做士兵或猎人），波罗蜜的文化（道德的完善，如慷慨和冥想），过纯粹和无害的生活，忠实的学习，实践和尊敬大般若涅磐经，不断的冥想佛永恒的观念的修炼，不变的和不灭的。

Therefore, we often said easy is road of the change, but did not say easy to have the invariable principle, because the change is absolute, but the invariability is relative, and, also is simple.

所以，我们常说易是变化之道，而不说易有不变之理，因为变化是绝对的，而不变性则是相对的，并且，也是简易的。

In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.

在匹配过程中，以向量之间夹角的大小作为相似度度量，直接利用图像的灰度信息在高维向量空间中考虑图像之间的相似度，克服了在低照度、低信噪比的图像中求边缘、角点、梯度和形状等特征的困难，不受向量模大小以及向量平移的影响，即相似度的计算是线性光照不变的。

The invariant gives us a useful property that helps show that the algorithm is correct.

循环不变式是一种误导。因为这是一种性质。一种属性。而不是表达式。
