向量分量 meaning in English

component of a vector
vector component

To solve the overflow or underflow of the components of appearance attributes caused by watermarking , we clip the error ones to the correct ranges by adjusting the corresponding basis function elements . the normalization operation would destroy the watermark embedded in the normal vector . the author presents a novel approach by rotating the normal vector around a fixed axis , which will modify its orientation , not magnitude
其中，针对在外观属性分量上植入水印的值溢出问题，作者提出了动态修改基函数的方法；考虑到直接修改法向量分量的方法会受到法向量单位化操作影响导致水印提取困难，作者提出一种绕固定轴旋转法向量的方法，有效地避免了单位化对已植入水印信息的影响。
