1.
However,the component-wise methods were only used in the early time and a large amount of research indicates that the vector filtering methods are more efficient than the component-wise methods since the vector processing based methods can preserve better the spectral characteristics of color images.
彩色图像滤波技术可以分成标量滤波法和矢量滤波法两大类。

1.
At the same time, by introducing direction vector into the GVF model, in the region specified by this vector, the force fields of the objects not wanted can be shielded, and the interested ob.
同时,提出在GVF模型中引入和设置方向矢量的算法,在矢量指定范围内能屏蔽掉不需要的物体力场的影响,从而更加准确地分割出感兴趣的物体。
2.
A time varing forgetting factor and a new correlation function adaptive filtering algorithm are proposed by orthogonalizing the previous direction vector to the current direction vector.
把相关函数最小二乘准则中的遗忘因子视为时变的遗忘因子,应用最速下降法使当前时刻的方向矢量正交于前一时刻的方向矢量,从而获得时变的遗忘因子的表达式,得到一种新的相关函数自适应滤波算法。
补充资料:伯格斯矢量
分子式:
CAS号:
性质:是位错尺寸的量度。当位错在晶体内滑动时,原子沿着某一特定的方向相对于其邻近原子切变了某一特定的距离,表示这种原子位移的矢量定义为位错的伯格斯矢量。对螺型位错,位错线平行于伯格斯矢量;对刃型位错,位错线垂直于伯格斯矢量;对于混合型位错,位错线斜交于伯格斯矢量。
