用变参数灰度共生矩阵提取新疆民间艺术图案纹理特征

为了较好地表达新疆民间艺术图案的纹理信息,选用可变参数的灰度共生矩阵提取其纹理特征。首先,在新疆民间艺术图案库上测试变参数对关键特征统计量的影响,并给出特征值与变参数之间的变化曲线,从而选定使纹理特征稳定的可变参数范围;然后,通过旋转、加噪、改变图像大小考虑算法的鲁棒性。本文的实验结果对新疆民间艺术图案的纹理特征提取具有参考价值。

Texture feature extraction of Xinjiang folk art patterns based on varying parameters of GLCM

In order to better express the texture information of Xinjiang folk art patterns, variable parameters of the Gray Level Co-occurrence Matrix (GLCM) were proposed. First, by testing the effect of different parameters on the important features of Xinjiang folk art patterns, the relationship between the features and different parameters was obtained. The ranges of the variable parameters to make the texture feature more stable were determined. Then, the robustness of these features was analyzed when the image was rotated or its size was changed or noise was added. Experiment results provide valuable reference for extraction of texture features of xinjiang folk art patterns.
