| 摘 要： | 提出了一种用于织物疵点检测的自适应正交小波基的构造方法.该方法从小波滤波器系数满足的正交归一化条件入手,采用一定数量参数角的正弦和余弦函数构造出一定长度的正交小波滤波器系数的统一解析式;以分解子图中像素最大能量值最小作为逼近条件,采用遗传算法作为寻优算法,从而实现针对不同的织物,自适应地构造小波基.同时,实验证明了自适应小波基的对疵点图像分解效果.

| Abstract: | A new construction method of adapted orgthogonal wavelet bases for fabric defect inspection is proposed in this paper. In the method, an arbitrary length wavelet filter coefficients with orthgonality and normalization can be constructed to uniform analytic form by using sine and cosine trigonometric functions of some parameters. Adapted wavelet bases are selected for different fabric by using max of each pixel gray in decomposed sub-image being minimum as sufficient condition, and genetic algorithm as optimization method. The decomposed validity of the adapted wavelet is proved by experimental resuits. |
