共生

Characteristic number of inertia moment of gray level co-occurrence matrix can reflect the feature of complexity of image gray space. Optimum space coefficient of LOG operator can be ac-quired effectively and most noise of images can be removed.

通过纹理分析，利用灰度共生矩阵惯性矩特征值能够反映图像灰度空间复杂度的特性，成功获取了LOG边缘检测算子最佳空间系数，抑制了图像中的大部分噪声。

The method optimizes the features according to the class separable criterion of margin of within-class and among-class distance and selects the optimized feature vector combination based on four kinds of features,such as gray histogram feature,wavelet transform feature,gray level co-occurrence matrix feature and moment invariants feature,with 26 dimension feature vectors in all.

针对冷轧板带材常见表面缺陷图像识别的特点，提出了板带材表面缺陷多特征优化组合方法，该方法以直方图统计特征、小波变换特征、灰度共生矩阵特征、不变矩特征等4类特征共26维特征向量为基础，依据类间类内距离差的类别可分离性判据对特征进行优化，选出最优特征向量组合。
