滤波函数 meaning in English
filter function
Examples
- It applies an interval method to select element in the evolutionary structure optimization method ( eso ) , and recovers or deletes element by the “ birth and dead ” function of element . another method viewed as second order smoothing technique for suppressing the checkerboard patterns has been proposed based on the filtering function ’ s principle . then the above methods are applied to solve a temperature - controlling problem in the steady heat conducting field and a multi - objective topology optimization problem considering multiple load cases and coupled effect
本文基于ansysparametricdesignlanguage ( apdl ) ,提出渐进结构法中应用区间法进行单元的筛选,通过单元“生死”的功能实现单元的恢复与删除,根据滤波函数法原理提出修改的二阶棋盘格处理方法,并就稳态热传导温度控制问题,考虑热、力耦合的多载荷工况的多目标拓扑优化设计问题进行求解。 - In the part of image preprocessing , a segmentation algorithm for fingerprint image based on the information of gradient orientations was programmed . according to the uniformity and partial parallarity of ridges and furrows of fingerprint , a model of gabor filter was established to enhance fingerprint image . since two - dimensional gabor filter could be separated into two one - dimensional filters , the complexity of the algorithm could be reduced efficiently
在图像预处理方面,利用指纹图像梯度特性进行图像分割,根据指纹纹线间距均匀且局部平行的特点,建立了用于指纹图像增强的gabor滤波函数物理模型,并将二维gabor滤波分解为两次一维滤波,有效降低了算法的复杂度。
