moment vector meaning in Chinese
力矩矢量
力矩向量
Examples
- Based on the three new supposition and the tow new mechanical tools : moment vector and radius vector , the warping theory introduced the analytical method of the rotation of a cross section around a fixed axis , so as to make the space stability of the thin - walled member complanate and one - dimensioned
翘曲理论以三条新的假定和新建立的弯矩矢量和转角向径两大力学工具为基础，提出了绕定轴转动的分析方法，使薄壁构件的空间变形平面化、一维化。 - The sticking point is when getting the wavelet modulus maximum , setting a limit value , only those larger than the limit value can be recorded , and the limit value is dynamic . so the remaining wavelet modulus maximum can best display the important characters of the image . after compute the seven invariant moments through using the wavelet modulus maximum of the image , similarity is given by the euclidean distance between two images " normalized moment vectors
改进之处主要在于，在求取不同分辨率下的模极大值时，设定一个阈值，只留下当前尺度(分辨率)下模极大值大于阈值的那些模值，而且随着分辨率的增加，阈值不断的改变，这样就可以在求得的高分辨率的模值图像中过滤掉低分辨率下的已经使用过的信息，从而使模值能够充分描述图像的重要特征，然后利用多尺度下的模值求出七个不变矩，并进行归一化，采用图像特征向量归一化的结果计算欧氏距离来表示两幅图像的相似度。
