To handle this problem , a novel adaptive filter for orientation parameter design technique is proposed in this thesis according the theory of one - parameter transformation group . an algorithm for the convolution of this filter and an image is also given 为了解决这个问题,本文基于变换群理论提出了一种方向自适应滤波器的设计方法;给出了这个滤波器与图像卷积的算法。
The information along 3d maximum shear stress tracing line is completely ascertained with the method of parameter transformation , then the changing rule of the normal stress along 3d maximum shear stress tracing line is discussed based on cobevel method 摘要利用坐标变换法证明了一般三维塑性流动问题任意点应力状态,可以完全由三维最大剪应力迹线上的信息确定,进而利用共斜面法给出了三维塑性流动问题沿最大剪应力迹线正应力的变化规律。
